Hi all , I have an options field in my paypal code where people need to select a colour, currently it is not being treated as mandatory and if people miss it out it comes through with that part blank. I need to make that field mandatory. Here is that part of the code. I believe you need to use javascript, but I don't know how. Any help would be very much appreciated, I have posted on other forums and have had no replies Dee <INPUT type=hidden value="Colour " name=on0> (**REQUIRED**) Please enter colour </TD> <TD> <SELECT name=os0> <OPTION value="none selected" selected> Please select a colour </OPTION> <OPTION value="Black"> Black </OPTION> <OPTION value="Green"> Green </OPTION> </SELECT> </TD> </TR> </TBODY> </TABLE> <BR> <INPUT type=image alt="Make payments with PayPal - it's fast, free and secure!" src="https://www.paypal.com/images/x-click-but23.gif" border=0 name=submit3>
