Your best option is any of the field scripts that trigger when an option is selected from the drop down. My favorite is the Keystroke script on the "Format" tab, when the "Custom" option is selected.  For scripting purposes it is best to have a direct relationship between the options in the dropdown and the OCGs (Layers). I noticed that the OCGs on the PDF are named "Layer 1", etc. These names make the scripting more complicated, because you need to somehow relate "Layer 2" to "USA". For example, have the OCGs named for the country, so the OCG name and the dropdown name are the same, i.e. the layer for USA is named "USA". Or have them in the same order so the index if the dropdown selection is the same as the position of the the OCG in the returned array. I don't like this one cause it's hard to manage.  Here's an example that assumes the names are the same. In Format Keystroke script if(event.willCommit)   this.getOCGs().some(function(a){return a.state = (a.name==event.value);}); To use the code you'll need to do two things, 1. Rename all layers to their country names 2. Flatten out "Layer 1", since it is the main background for the document. ... View more

If you are using the stamp in Acrobat Reader, then saving stamp data into the document is a problem.  There are some possible replacements, but it all depends on your objective. Is it important to save the data on a per document basis? or could it be saved globally? Does data need to persist across Acrobat sessions? You might want to re-read the Chapter 8 section "Data Storage and Persistence" ... View more

Hello Jeremy,       To start, just as a helpful communication tip. It is a good idea to try and post code with proper formatting so we can follow it. This is especially important for large scripts. First thing to do, remove the "event.value = app.response" line. Just looking at the code there is one glaring issue. "event.value" refers to the value of the form field in which this calculation script is placed. Yet it's used for all the response boxes. For setting the other field values you need to use "this.getField().value" Typically, if the response box is popping up when you show the stamps menu, then the response box code is unprotected. This is because the stamp script is executed every time the stamp menu item is exposed. However, you're script does protect the calls to app.response. So your description and the code you've posted don't match. There must be other code in the stamp file that is displaying the response box. There are two ways to approach a fix. 1. Delete all code in the stamp file and start over with one response box in one field calculation script. Once you get that working, then try another, and remember, all calculation scripts must be protected with the first if statement in your code above. i.e. the if that use "event.source.forReal" 2.  This is the really easy solution.
