"#!" must be the first characters in the file, and they're not.	[reply]

From what is printed here, the file looks ok as far as format goes. Sometimes there can be a bad character which is not a printable character and that messes things up, but I figure that's unlikely here. I would fist look at the permissions on glcashbyfund.pl and make sure that it has appropriate read as well as execute permissions so that it will run when user clicks within this page: http://cgi.portseattle.org/mis/gl/glactivityreportmenu.html.

You could try running the script from the command line and having a look at the headers it produces, I would be willing to bet that it is spitting out something other than a header prior to the header itself and thus causing the error.	[reply]

The most likely problem is that the environment variables needed by Sybase OpenClient (and so by Sybase::CTlib) aren't defined. These should be defined in the http server's config file (SYBASE and maybe LD_LIBRARY_PATH) Michael	[reply]
