Hi there,
 
I'm new to using Acrobat, and I'm getting confused about something I thought was simple.
 
I am using LiveCycle Designer 8.0 to build a form. basically, what I want to do is change the presence of an object on the form based on user input. For example, I have two objects on my form: a dropdown list (DDList1) and a text field (Txt1). Initially, Txt1 is invisible. What I'd like is when a user selects a particular value from DDList1, then Txt1 becomes visible for them to input text.
 
I'm having trouble figuring out the proper syntax. The scripting language doesn't matter (FormCalc or JavaScript) - whichever one is better works for me.
 
Thanks in advance!
 
Cheers,
Shawn

Stick with javaScript for this one. The exact syntax depends your form's hierarchy, but here's the basic code you should have in the "Change" event for the dropdown list.

if(xfa.event.change == "MyValue")Txt1.presense = "visible";elseTxt1.presense = "invisible";
