Sorry, I know this is for the wrong group - I just started here as the major
part of this app is related to a data base - this is just the fancy stuff at
the front. I have been able to get the screen to redraw by putting a
variable in the url that when set causes a tag to be sent with a
refresh option - it is ugly as it causes the screen to draw then immediatly
redraw. I have tried all combinations of header()'s but I am missing something.
Thanks,
Malcolm
