How to make script which validates entered IBAN?

[Test Screen Name]

1. Learn JavaScript programming.

2. Research the IBAN validation code rules (which will include format and likely a checksum of some kind).

3. Turn the rules into an algorithm.

4. Turn the algorithm into code.

5. Add the code as a validation script.

6. Find it doesn't work and endlessly repeat most of the above until it works.

I agree with gkaiseril. I have such a script but it's not free.

You can contact me privately.

I would use the "Custom JavaScript" on the "Validate" tab for the field where the IBAN is entered. It looks like you will need to use the RegExp to validate the format of the entered value and split the value into the various parts for additional processing. This is a very complex script and I do not think you will find any volunteer willing to give you the coding for free.

This will be quite a project since there are many countries each with a unique format that needs to be accounted for and tested. Just look up the standard.
