Prompt on year in web I report

Hi All,

I have a report with year ,quarter & sales revenue objects.

There is a prompt on year and year contains 2004,2005 & 2006.

Now my query is If I select one value 2004 that value should not be displayed in the report.

Also If I select two values 2005 & 2006 that values should be displayed in the report.

Kindly give your valuable output over my concern.

Thanks

Ram
