Hi Brian,

as I see the value of the submit button doesn't pass to the next form, I 
see that when I using HTML page and pressing on the 'submit button'.
so, I understand that I should check it not by using cgi.params[..][], 
but by other command.
can you tell me if what I am say is right ? and if so can you tell me 
hoe to check the value of the submit button.

another question :
if I want that one of the submit buttons will update the current form 
with the adittional line, and the other submit button will update other 
form, how can I do it using only one form and two submit buttons ?

I appriciate your quick answer,
Thanks,
Asaf
