Trouble getting a value from a palette

[byronnash]

I have a basic palette with an EditText object on it. When a button is clicked, I run a function that executes the bulk of my script. When I try to add in a variable in the onclick function to read the text of my EditText, the script quits executing. Is there anything special I need to do to get values of UI elements to be readable in onClick functions? I have a checkbox that is working correctly on this same palette.
