Cannot not open On Edit On Success script

Cannot not open On Edit On Success script

I cannot access my On Edit On Success script for my application: http://creator.zoho.com/carlgifford/vacation-rental1
Form: Rental_Agreement

I just cycle with "Loading" message.

Can this be fixed?  I have a lot of work completed on this form!

Thanks for your assistance!
