Crosstab date parameter

Hello,

I have a Crystal Report 2013 that is a crosstab based on a date. I created 2 parameters for begin and end date. In the selection formula I have

{vw_ADJ_Down_UP_ALL.allocatedate} in {?BeginDate} to {?EndDate}. When the report runs it returns all the dates that in the underlying view and not the range I specify. Also, the pivot is based on the above date column. Why is this?
