Thanks Richard,
I changed from using <img src=graphit2.php> to <a
href=graphit2.php>graph</a> and now get my graph, on a page of its own,
without any error messages. Works just fine, or will, when I change how it
gets its data. However, I do want to have the graph display on a page with
other information so I'm back to wanting to use some sort of image tag. Any
suggestions?
Hugh
