checkBoxList control email results

I have a form (http://www.readwritenow.org/pages/vo...ntakeForm.aspx) the results of which need to be e-mailed.

The checkBoxList control is populated manually, there is no database involved. In the interest of your time, I have removed the textBoxes and dropDownLists from the .cs below since they behave perfectly.

The problem I am having is the checkBoxList control is returning only the first checked selected item, not all items selected.

I'm a newbe and in over my head, so please treat your response accordingly.

Thanks for your help!
