Hey guys new to Javascript.  This is supposed to be a validation script so that people will have to fill out all fields before they submit the form.  When I upload this to server to my site.  it isn't working.  Any ideas?

Do you realize that JS can't be considered validation? It should be viewed as nothing more than a convenience to the user when properly implemented, or a huge hassle when improperly implemented. You must validate the data in the server-side language after the form has been submitted.

Frankly, no, it won't. Moreover, if the form is used to insert into a database, you'll end up with either a compromised database, or one that ends up getting deleted by some script kiddie. If this sends an email, you're going to have every spammer in the world using it to send spam in no time flat. All a user has to do is disable JS, and they can submit any value they want to submit. That's why server-side validation is crucial.
