	edit the paramter under List of values make it Dynamic in the Valuer column selct the source field (Service) in teh Paramter colum click and add your name I assume here you wanted cascading params that are dependent on the previous selection int he second row in the value column click and select 'Category' field and add teh param name in the paramters column. repeat for sub category

	I tried it, but I don't know what happen in Crystal Report. When I create a parameter, just only some value in 'Service' show on the 'add list'. It didn't have happen before :( I run the query in SQL, it shows all records, but in Crytal it lost some records Anyone know what wrong in the Crytal Report?

	The Crystal Report version is 11.5.12.1838 The day before Yesterday I had another report, after I change the INNER JOIN in the query to the FULL OUTTER JOIN, then I got the all output. But yesterday, I did another report, I also tried to change the INNER JOIN to FULL OUTTER JOIN, but it still lost the data and can't prompt all parameters.
