I'm confused.

The controls on the page seem simple enough in that they assist the user in filtering the dataset which is provided through the SQLDataSource...

It actually works, but it's just that the CheckBoxList is not set up to push multiple values through to the 'Course' parameter. That's where the For Each statement comes in.

Won't I have the exact same issue if I go about the back-end connections a different way?

Seems to me the snag I'm up against is how to appropriately configure the web control, specifically the CheckBoxList so that it passes multiple values (string into the Course parameter)...
