Validating Custom Attributes

Does anyone know if there is a way that I can validate Vendor Attributes?

When creating them, I can set a type of textbox, but really the value should be a number

Is there a way to validate this when a user submits the vendor application form?

It requires customization.  E.g., you could  use JavaScript code to listens for the input event on the custom attribute input field and check the input value against a regular expression.

Alternately, if the 'list of valid numbers' is small, you could instead use a drop down type control.

Thanks,

I've been able to validate this with some custom code

Feel free to share your solution here :)
