	I am using a date paramenter in my report and would like to compare two date fields in two different tables. Not sure if there is a crystal function. Any help with this would be great.

	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 Edited by rahulwalawalkar - 28 May 2009 at 7:11am

	I am using both tables in the report. Basically a user would enter the date when the report is being run and that value will match it to the date in two different tables. I think I have to write some logic behind it. Edited by brent21090 - 28 May 2009 at 7:17am

	Hi the code should work in your record selection formula enter {table1.datefield} = {?prm_date} or {table2.datefield} = {?prm_date} caution :- this eturn records if the user entered date exists in any one the tables {table1.datefield} = {?prm_date} and {table2.datefield} = {?prm_date} caution :- this return records if the user entered date exists in any both the tables As I said before you need to tell us what is the report suppose to do once the user enters the date in the date parameter ? cheers Rahul Edited by rahulwalawalkar - 28 May 2009 at 7:27am
