I am using a web trends connection and need help solving an issue with my MS Query that includes Parameters. Data is returned for specific date Ranges but not when Parameters are applied.

My tables include [StartDate] and [EndDate] which is where I need to place my Parameter
I also noticed in the SQL tab that it was noticed as a Time Stamp. Time display ex: 01/01/2012 23:59:59

Does anyone know why data won't return?
