Form Validation Help Needed Please

[chimp]

I am knew here so hi to everyone, I have been told by a friend that this site is particularly helpful so here goes.

I have a form that i want to ensure is filled out correctly before the user is able to proceed. I am also advised that Javascript is the easiest way to do this, however i have no idea how to implememnt it.

http://chimp.cc/start.htm

If the user fails to fill out the terms and conditions box with a "Yes"when the user clicks submit, i want a message to pop up to tell them to complete it.

and to return the user to that field for completion.

I honestly have no idea how to do this, can someone please help me.

I have attached the source code too.

Cheers

Andy

It looks like you already have something?

anyway if you dont, all you need to do is use:

document.getElementById('id_goes_here').value to get what the items value is...

then do an if statment to see if it fitts your needs

then in the <form> tag make an element called 'onsubmit="return yourfunction()"' then have that function do a "return true" if the form is acceptable, and "return false" if it is not. and if you want to add a little message use alert() function http://www.wikijs.com/index.php?title=Alert

if you return false to a onsubmit it will not submit the page.
