Help needed with the Report Grid (Dataset OQL) using a parameter

We are trying to make a report using the Dataset functionality of Mendix. This is working perfectly and very very fast, but whatever i try I cannot use a variable/parameter inside the query. I know it must be something very silly, but I am truly stuck. I hope there is some one who can help. I add a few printscreens so you can see what I am trying to do. Your help is very appreciated!
