Generate report problem (even more problems): data filtering problem

I still even have more problems of generating the report. My project is due next week.
Even when I tried to change the source code and code-behind, it still gives me the same data filtering problem - showing all the data instead of filtered.
I've changed to the number-based value of the Internet Access, NSF, and Loan Computer in both report and GenReport.
When I want to select all the data filtered in report.aspx, it gives me an error:

Cannot perform 'Like' operation on System.Int32 and System.String
