The messaging that you are seeing is not an error, but rather a notification that a variable has not been defined (yet). This is a warning and will not actually prevent the Constant Contact Signup Form Generator (CCSFG) from running.
To suppress these warning messages, you can modify the error_reporting value of your php.ini file to:
error_reporting = E_ALL & ~E_NOTICE
This will continue to display error messages, but will prevent notices like this from being seen.
I hope this helps. Please let us know if you have any other questions and we will be glad to help.
