Destroy_Parameter_List(PL);
End;

Potentially several problems here. First off, you are passing NULL values into the parameters because D1 and D2 are unassigned. Second, you are creating two separate parameter lists, so only one of the two dates gets passed to the report.

You also mention that the text item does not allow you to enter a date. What error message are you receiving, and what are the names of the fields that contain your dates?
