Looks like you're calling an unmanaged report?  You should be able to just append to the URL:

$code.= "\n\tlocation.href = './hcfa.rpt?promptex0=paramvalue';";

cyrilvictor - Sorry for the delay in response, but you posted in my feedback area so I didn't see it 'til now...

For everyone's reference the posting from asker was as follows:
-----------------------------------------------------------------------------
thanks for ur response but it is not working.
  i used the code as follows:
     $code .= "\n\tlocation.href = './hcfa.rpt?&visitid=2';";
  but it is not working, pls help me
-----------------------------------------------------------------------------

In this code you must replace "visitid" with "promptex0".  This is crystal-specific syntax - Crystal will look for the value assigned to promptex0 to fill the first report parameter.  If there's a second report parameter Crystal will look for the value assigned to promptex1, etc.
