Hi All,

I am trying to write test coverage for the following class that sends an email.  Any help would be greatly appreciated.  I'm a novice and I wrote the class in less than a day.  Now, I've been trying to write the test class for a week and can't get over 32% coverage.

The lines that don't have coverage are, 20, 25-28, 33, 36, 39-50, 55-57.

Please help!!!

Thanks
Bill Haberlin
