Im looking how to require a 3 digit code to be entered in the Referral code field. I have changed the verbage to now say Enter Salesman Code and made the field required. But i cant figure out how to make it require 3 digits and to match 200,300,400,500 etc.. i would like it to only allow the account to be created using only those numbers, that way not just anyone can create an account. The other reason is that if there is a code entered, i can use the referral report to be able to know the exact amount each salesman has under thier code. I am using ver 1.3.8. Thanks in advance!!!
