My form has an option for the user to delete subforms/records as needed. Acrobat does allow for Undo- so if my user accidentally clicks "delete", they're stuck.
I added an alert box to ask "Are you sure...", with "yes" and "cancel" buttons. But when I click the cancel button, it deletes anyway!
Here is the script I'm using:
if(xfa.host.messageBox("Are you sure you want to delete? This cannot be undone.","Confirmation Required !!!",2,2)==4)
and here's the form:

That's brilliant - thanks radzmar!
