which I used, and it works just fine, except that I just discovered
that if I place just a litle more than a few line of text - in the TEXT
fields then i get an "error" in phpmyadmin. There is a small question
mark were thre is normally a pen and a cross - and when I move the
cursur above the question mark i get this. "you should define a primary
key for this table" .

Do you have any suggestions as to what the problem might be?

Thanks for any help you can offer.

Best regards
