      Hi Brock ,

      Thanks for your reply , I have a main page where i retrieve Query paramters and pass it on to different .asp pages depending upon choice , I was already doing this
      $start_date = $Request->Param('Start_Date');
      $end_date = $Request->Param('End_Date');
      $format = $Request->Param('Format'); and then i was doing this again

      my $Sdate = $Server->URLEncode("$Start_Date");
      my $Edate = $Server->URLEncode("$End_Date"); , i have removed this it works fine.

      I tried generating Graphs in .asp page , it was clashing with ASP code and generating error like GD::Graph not declared and few times i would get inconsistent Graphs and hence reverted to Generating Graph's using Perl.

      Regards

      Raghu

      In your code you should be able to read in the params like this:

      $start_date = $Request->Param('Start_Date');
      $end_date = $Request->Param('End_Date');
      $format = $Request->Param('Format');

      And you will get the decoded values (i.e. %20 gets translated to a
      space, etc.)

      ...or are you not using Apache::ASP in Graph.pl? What are you using?
      CGI.pm module? (should still work...) Can Graph.pl just become Graph.asp?

      ??
