1. Example 1 : Ask SQ2 only if yes in SQ1 for the L1 loop items 1 &3
2. Example 2 : How to check that the sum of the values given to all loop items is equal to 100% ?
3. Example 3:  Ask Q6 only if  yes  to all iterations of L4
4. Example 4:  Routing with loop of loop
5. Example 5 : Recode each "yes" in the sub-question into a multi coded

Askia provides an original way of dealing with sub-questions, question tables and level issues : loops.
A loop is a question hierarchy and can be handled with at least:

- 1 loop question (eg L1)

- 1 sub-question  (eg  SQ1 Do you intend to buy the following brand  ? Yes, No)

There are 4 types of loop:

- question table

-  loop with selection for each iteration

- loop with preliminary selection

- loop with iteration count entry

The same routing syntax can be used for all loop types.

Example 1
 

Ask  SQ2A only if we have "yes" for the SQ1A and for the L1A loop items "Ariel" and "Ecover"

Depending on the loop layout you have chosen you have 2 options:

A. Chained SQ1A-SQ2A for the same iteration

• L1A is the Question table loop with the following items

And set to 1 for the maximum visible iterations:

• SQ1A is the first sub-question with the items

The routing will be :

' Loop items 1 ('Ariel') and 3 ('Ecover')
' and SQ1A = 1 ('yes')

The AskiaScript 'CurrentIteration'  refers to the current iteration of the loop while 'iteration' refers to a specific iteration of the sub-question.

B. Firstly all items for SQ1B and then only items concerned by the routing for SQ2B

The loop L1B will be a Table question loop with:

• all max visible iterations and
• the same list of items we have in L1A.

The Loop L1C will be a loop with preliminary selection:

• 
• all max visible iterations and
• the same list of items we have in L1A.
• linked to the same level as L1B (in order to align result in Analyse for SQ1B and SQ2B)

The routing will be :

' Loop items 1 ('Ariel') and 3 ('Ecover')
' and SQ1B = 1 ('yes')

 *Value if true : We keep the content of L1C and add the new L1B iteration value

**Value if false : if the respondent go back and change the value , we want to remove the previous value  from the L1C values

Example 2 - How to check that the sum of the values given to all loop items is equal to 100% ?

We propose 2 methods.

A/ Set a logic check within the loop

The routing will be :

Start question	SQ3
Condition	' We run the script on the latest iteration of the loop ' and we check the sum of SQ3 <> 100 (L2.IsLastIteration) and SQ3.allvalues.sum() <>100
Action:

B/ Set a logic check outside the loop

We add a chapter 'Sumtest' outside the loop.

The routing will be:

Start question	Sumtest
Condition	'we check the sum of SQ4 <> 100 dim sumresult = 0 dim i   for i = 1 to L3.responses.count  sumresult = sumresult+ SQ4.iteration(i).value  next i if sumresult <> 100 then return true EndIf
Action:

N.B. Whatever the method, we invite you to help the respondent by adding an automatic sum on the screen.

To do it in the example 2A , add a label and insert the following script:

</br></br>
Total remaining % to share : 
<b>
 !!on(SQ3.allvalues.sum()<>100,
"<span style='color:#DF4335;'>" + (100 - SQ3.allvalues.sum()) + "</span>",
"<span style='color:#00FFC00;'>" + (100 - SQ3.allvalues.sum() )+ "</span>")!!

 </b>

In the example 2B, add the script in the Sumtest chapter title:

Total remaining % to share : 
<b>
 !!on(SQ4.allvalues.sum()<>100,
"<span style='color:#DF4335;'>"+ (100 - SQ4.allvalues.sum()) + "</span>",
"<span style='color:#00FFC00;'>" + (100 - SQ4.allvalues.sum() )+ "</span>")!!
 </b>

Example 3

I want to ask Q6 only if the respondent answered yes to all items of the loop L4

Add a chapter outside the loop to set the start question routing.

The routing will be :

Start question	FilQ5
Condition	dim i  dim z = L4.responses.count dim result = 0 for i = 1 to z    if SQ5.iteration(i) has {1} then          result = result +1        end if next i if result = z then     return true end if
Action:

Example 4

Set a routing on loop of loop

The top loop is L5, the sub-loop is L6.

We want to ask SQ8 when top loop (L5) =place2 (2) and sub-loop (L6) = Ecover (3)  and SQ7=Yes (1)

To create the routing, you need first to set the iteration wanted . . .

((L6.currentiteration has{3}) and (L5.currentiteration has {2})) 

 . . . and follow the syntax "QuestionShorcut . iteration(Sub loop:X, Top Loop:Y)"

 (SQ7.iteration(L6.currentiteration, L5.currentiteration) has {1}) 

The routing will be:

Start question	SQ7
Condition	'Top loop = L5 'Sub loop= L6 'We will ask SQ8 when Top loop=place2 and Sub loop= Ecover and SQ7=Yes ((L6.currentiteration has{3}) and (L5.currentiteration has {2}))  and (SQ7.iteration(L6.currentiteration, L5.currentiteration) has {1})
Action:

Example 5

We want to recode into a multi-coded (SQ10),  each "yes" in the SQ9 sub-question.

Recode each "yes" in the sub-question into a multi coded

Anytime the respondent said yes (SQ9=1) for an iteration of the loop (L7), we want to recode the iteration into the multi coded question (SQ10).

You can set the recode routing in 2 different ways:

a)  After each iteration in the loop

The routing will be :

'loop = L7
'subquestion =SQ9= L6
'We will recode only if we have SQ9=yes

 *Value if true : We keep the content of SQ10 and add the new L7 iteration value.

**Value if false : if the respondent go back and change the value , we want to remove the previous value  from the SQ10 values.

b)   Outside the loop

The routing will be:

True

' we declare 2 temporary variables : 'i' and 'result'
dim i
' we initialize the variable as empty
dim result = {} 

For i=1 to L7.responses.count 'responses.count = max value in the list of brands
if SQ9.iteration(i)= 1 then 'For each SQ9=1 , we add to 'result' the corresponding iteration value
result = result + i
endif
next i

return result
