Help with script

[Rachelle5EBD]

Looking for a script that will prevent users from putting entries in both colum A and  B of fillable pdf fields. If you put something in colum A, then nothing can go in column B. Likewise, if something is in colum B, then you can't have something in column A.

You can set fields to readonly, lets say you have fields "A" and "B" if field "A" have value field "B" is readonly and vice versa, as validation script of:

 field "A":

this.getField("B").readonly = event.value == "" ? false : true;

field "B":

this.getField("A").readonly = event.value == "" ? false : true;

Thank you for your response. I tried putting in the script, but it's giving me a syntax error message.

Can you post script you tried to use?

[Rachelle5EBD]

I used the script you provided, but replaced the "A" and "B" reference to my form field names.

Those are 2 scripts, one for field "A" second for field "B". 

Script for field "A":

this.getField("B").readonly = event.value == "" ? false : true;

Script for field "B":

this.getField("A").readonly = event.value == "" ? false : true;
