alert("Please enter a valid email address");
return false;

Form validation of the pattern if(myTextField.value == ") is barely worthy of the name, and virtually useless, as even a single space, an X or a ? will return false, that is pass the validation. Numeric values, such as zip codes and phone numbers, should be validated as such. Ditto email addresses. This topic has been covered many times before in this forum.
