Is there a way to hide a field in a query?

IE) I have 15 different courses, each with a startdate and an enddate
The table goes as follows


ID Name Course1 SD1 ED1 Course2 SD2 ED2...etc


I only want to display certain courses, with their start and end dates, on a query if their course matches the one selected in a combobox.

example output (fields only) would be



ID Name Course3 SD1 ED1 Course 8 SD1 ED1...etc


For the record, I am really starting to hate Access
