+My contribution is checking wheather email id format & mobile number format are correct or not during Catalog item Form Submission. Expected Email id Format - "abc12@gmail.com" & Expected Phone number Format - "123 -567 -6789"
+If Format match system will allow to submit the Form or else restrict submission of the form.
