Error when Executing Test for function

Error when Executing Test for function

I am creating a function, but when I execute it, this is what I get:



The function does not seem to be working because it should send an email but is not.
But there is no description below the blue header like one usually sees to tell what the error is. Instead, nothing happens.

I've shared my Summer Camp Online Registration & Management with support.
This is the CampReminderForMonday function.

I'm using Firefox 4.0.1 on Windows 7.

Thanks for looking into this.
