Stateless Form "Error at on click script."

Stateless Form "Error at on click script."

I have a stateless form in a creator app.  It has an onload script and a on-user-input script.  Both use values in the form to calculate and populate other values in the form.

I added an onclick script for my submit button, and regardless of the contents of that script, when I click the button, I get an alert that reads:

"Error at on click script.  Note:  We are working on giving more meaningful error messages on script failures."

I have tried making the script empty, only having an assignment (eg. x = 10), using openUrl to redirect, using info or alert to print something out.  It doesn't matter what I put in that script, the error is always the same.

I then tried adding a new button (not the submit button) and attaching the on click script to that button.  But it gave me the same error.

Any ideas?  Could this be on Zoho's side?
