Thanks dev. :-)

Don't rely on client-side javascript validation. It can be disabled and then your script has no protection.

Always have server-side validation.
Here is an example using simple If/Else statements

degsy, thanks for your example.
Indeed, if an user had JavaScript disabled, my validation script it's useless.
