I've never used Crystal Reports before yesterday.
I have 2 questions: Using VS/VB2010
Why don't all my datasets show up in the list when I go to create a new report.

I was able to create a new datasource and create my report, I was able to preview the report, all was great data looked the way I wanted, however, as soon as I recompiled I got a boat load of errors.
Below is 2 of my errors, what did I do wrong?
Thanks
