Why won't my buttons work?

I am really embarassed to ask this question, but I simply cannot get my buttons to work.

• I'm working in LiveCycle 10.4.2 / SAP OEM
• I have set my form to be dynamic.
• I'm targeting Reader v 9 or higher.

I added a button called "Click Me!"

I added the following script:

data.JP_Page1.sub_MentorAddress.Button1::click - (JavaScript, client)

alert ("Hello World");

When I preview or test the form in my dev environment (i.e., with data merged, saved as a PDF, and opened on my local machine), the cursor changes to an I-beam over the button and I cannot click the button as I would expect to.

I thought that maybe there were security issues related to raising an alert from a PDF, so I also tried to set the value of a text field on click, but that did not work, either. I've tried both FormCalc and JavaScript. No go.

I must be missing some basic setting, and I cannot figure out what it is.

Any ideas would be very much appreciated.

Thanks!
