How can I set fields to collect bank details and validate them?
I would like to collect bank account number and sort code.
Bank account has a set number of numbers which I guess is quite straight forward.
A sort code has 3 groups of 2 digits. Could it be set so once 2 digits are entered then it added a hyphen then another 2 digits and hyphen again then another 2 digits.
I have seen on some forms that the sort code is created by 3 separated fields that only allow 2 digits. Can a value be be created from 3 small fields?

To create 2 fields in a row I simply added a 3 column row and added 3 separate fields. Sortcode1, sortcode2 and sortcode3. This I removed the labels and padding from sortcode2 and sortcode3 using css.

Looks on for the bank sort code in the field but just have to remember to use all 3 values in order to create the3 sort code.
