Acrobat form javascript display text in one field based on value of other fields

[karenl32644045]

Hello to everyone, and thanks in advance for any help.

In my pdf form, I have 8 fields that are answers to questions -- each field has a drop of yes or no. I've given yes the value of 1 and no the value of 2.

There is a 9th field (Advice Document) -- it is supposed to display text based on the yes/no replies to the 8 questions. Plus, it should display default text before any questions are answered or if a condition is not met.

Here is a screengrab of the field layout:

This is what I've come up for code:

=======

var q1 = (this.getField("Q1").value);
var q2 = (this.getField("Q2").value);
var q3 = (this.getField("Q3").value);
var q4 = (this.getField("Q4").value);
var q5 = (this.getField("Q5").value);
var q6 = (this.getField("Q6").value);
var q8 = (this.getField("Q8").value);

if ( q1 = 1) event.value = "Text1" ;
else if ( q2 = 1) event.value = "Text2" ;
else if ( q3 = 2) event.value = "Text3" ;
else if ( (q4 = 1) && (q1 = 1)) event.value = "Text4" ;
else if ( q5 = 2) event.value = "Text3";
else if ( q6 = 1) event.value = "Text3" ;
else if ( q8 = 1) event.value = "Text5" ;
else if ( q8 = 2) event.value = "Text2" ;
else event.value = "DefaultText" ;

=========

(note: Q7 isn't referenced in the code because clicking either yes or no should display the default text)

No errors are flagged, but this doesn't work.

As soon as I close the field dialogue, "Text1" appears in the Advice Document field. Selecting yes or no for any other field has no effect.

I'd be very grateful to anyone who can point out what I'm doing wrong! (Many things, I suspect.)

Thank you.

Replace

if ( q1 = 1 )

with

if ( q1 == 1 )

Change also the other if

Thanks for your help, Bernd. I changed all the =  to == in the ifs, but it didn't work. The result was the same, ie, As soon as I close the field dialogue, "Text1" appears in the Advice Document field. Selecting yes or no for any other field has no effect.

Where does you use the script?

[Nesa Nurani]

You need to place 'if' and 'else if's' differently.

In your script when 'Q1' is 1, value will be "Text1" and when that happen rest of else if's won't trigger because first if is true, so you have to reorder them, for example, try first Q8, then Q7...etc.

Thanks Nesa, your comment about the first 'true' stopping the script was helpful; I hadn't considered that! 
However, I have reworked it so that each Q has its own result. That is working, from a technical point of view (and I'm using == not = for 'value', as Bernd suggested). Now just to see if the job owner is okay with it!
FYI, each Q is now structured like this:
event.value = (this.getField("yn1").value == 1) ? "Text1" :
(this.getField("yn1").value == 2) ? "Default Text" : "";

Thanks for the feeback, it helped.
