hi
depends what you are comparing the date parameter
are you using both the tables in the report ,
where do you want to compare the dates?
in record selection formula it will be
equal to example below
if need to check >= or <= or <> change the comparison operator
{table1.datefield} = {?prm_date} and {table2.datefield} = {?prm_date}
cheers
Rahul
