Larry:
Thanks that was what I needed.
One thing I noted in debugging is that if I go to the edit entry page, don't make any edits but still click on the submit button I get the same error as reported above:
Since I didn't make any fundamental changes to the script I have to assume that this is the expected behavior. However, I assume that in a production situation this is something to be avoided?
Assuming that this is not a problem I created can you point me to any resources that describe how to overcome this behavior.
Thanks
