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.
