Changing the value of a previous question

I have currently set up a variable called isvalid which I am setting to 1 by default. When I ask q1, if the respondent answers this with a value of 2 I want this to reset the value of isvalid to 2.

I have set up a separate equation question with the following text in the question field - yet it doesn;t seem to be doing this validation.
{if (q1=='2',isvalid=='2',isvalid=='1')}

JavaScript is enabled and I am using v1.92 build 120909.

I think this is a simple problem to fix but just can't seem to work this out.

Many thanks

Is "isvalid" just a JavaScript variable or a question code?

As far as I know, you cannot use an equation question to set the value of another question.

You may need to use JavaScript to do this. (with a listener on q1)

Yep,

Or easy way:
QCODE: isvalid
QTEXT: {if (q1=='2','2','1')}

Thanks for this - that works fine for one questions.

If I was needing to revalidate the contents of isvalid later on (for instance checking if q5 was 1), how would be the best way to do this?

thanks

2 Equation question:

1st:
QCODE: isavlid1
QTEXT: {if (q1=='2','2','1')}

2nd (or at end)
QCODE: isavlid
QTEXT: {if (q5=='1' and isvalid1=='1','1',isvalid1)}

Think it worked.
