Hi,

I’m trying to prevent an email address from being entered that has more than one period in the name. For example:

[test.ing@gmail.com](mailto:test.ing@gmail.com) = PASS  
[tes.t.ing@gmail.com](mailto:tes.t.ing@gmail.com) = FAIL

Is there a way of passing a validation for this?

Thanks

Hi Ron,  
You could use the GF filter hook to prevent submission when someone inserts one more period on the email field. Here is the [documentation](https://docs.gravityforms.com/gform_field_validation/) of the detail. Let me know how that goes! 😄
