I tried your suggestions and got the same result. I am not seeing anything in the html that should be causing the hick-up, but given the php is run on the server as Peter pointed out, browser issues with php I have not really encountered before. I can live with a submit button, but living with one that does not work... Thank you for your input, if you see anything else that seems amiss, please let me know.
