Validation form code?

Question

ok. So I have these boxes-
First Name
Last Name
E-Mail
Username
Password
Re-Type Password
I also have a register button.
I have properly linked my javascript and checked for any
mistakes but when I click the register button, I get an error
saying that I am missing parts of my form where I want an alert box
to come up instead.
Attached is my Javascript.

Answer 1

What does the error message say, exactly. And can we see the
HTML?
By the way,
> errorMessage += "Please enter less letters.\n";
wouldn't you want to say "Please enter fewer letters.\n"?
> errorMessage += "Please choose select a button.\n";
I have no idea what this says....
