I need this too so hopefully someone can help.
As schoolboy points out, fax machines are the way of the dinosaur ;-) SO I have changed the text to something else - we need the customer to tell us whether their address is suitable for courier (simple yes or no answer will do) but I want the answer to be compulsory.
Adding an extra field for this seemed way too tricky and dont need the fax number so this seemed an easy way round it.
Would also like to make that field a bit longer.
Any suggestions??
cheers
