hi i have question type text array with the 1 row and the two columns. i need that answer field automatically filled based answers from others questions, those questions also text array with the 1 row and the two columns.. the calculation for my field q20/q16.

Hi,
read the manual about ExpressionScript.

You have to use a (hidden) question of type "equation", where you do the calculations and set the value in the next array.
Something like
{Q2_Y001_X001=Q1_Y001_X001/Q1_Y001_X002}

Adapt to your codes  and your calculation

i received on your code undefined variable

i resolved problem with next code Q33_SQ001_SQ001=Q20_SQ001_SQ001/Q16_SQ001_SQ001, but i have one more problem in question text array i have two field how i add next code


Q33_SQ001_SQ001=Q20_SQ001_SQ001/Q16_SQ001_SQ001
Q33_SQ001_SQ002=Q20_SQ001_SQ002/Q16_SQ001_SQ002

i received on your code undefined variable

What else did you expect? Of course we can only provide the structure as long as you do not show exactly your question codes / subquestion codes, etc.

i have two field how i add next code

Insert both calculatios into the equation



 

my question Q33 is text array type with the one row and the two columns (subquest) SQ001 and SQ002. i have also the two questions Q20 and Q16 that are the text array with the one row and the two columns SQ001 and SQ002.
i used next code

if((Q20_SQ001_SQ001 == "0") OR (Q16_SQ001_SQ001 == "0"), Q33_SQ001_SQ001 == 0, Q33_SQ001_SQ001 == Q20_SQ001_SQ001 / Q16_SQ001_SQ001), if((Q20_SQ001_SQ002 == "0") OR (Q16_SQ001_SQ002 == "0"), Q33_SQ001_SQ002 == 0, Q33_SQ001_SQ002 == Q20_SQ001_SQ002 / Q16_SQ001_SQ002) i don't know that this code ok

if i set my above code question is not displayed in survey

Can you include a copy of your survey? It's quite hard to visualise your issue. You can attach the .lss file

You are confused about the "comparison operator ==" and the assignment operator =".

Have a look at the manual about operators.

Joffm 

And do you really want to divide by "0"?
Your equation is something like{Q33=if(Q16==0, Q20/Q16)}

Furthermore your if-statement is wrong. The dyntax is the same as in Excel.
{if(condition, what to do if TRUE, what to do if FALSE)}

In the manual there are some examples, I think in 
"ExpressionScript How-to"

i corrected '==' to '=' but my question does not displays

i attached my survey. the problems are questions 33 and 34. those questions does not displays in my survey 

You have to use a (hidden) question of type "equation", 

There are no questions of type "equation" in your survey.
And you placed your code in "relevance equation". This is something quite different.
Please, learn the basics, study the sample surveys that you find in the manual
[url] www.limesurvey.org/manual/ExpressionScript_sample_surveys/en [/url]

And please, send only the relevant questions.
It is really difficult for us to go through a survey with cyrillic letters.

But, as I am courteous (most of the time) I will fix it. and send back.

Joffm
