Answer 2

im going to try my best here to help you. base on Ipang post, it looks like your javascript is running before the elements are created. i would imagine it could help if you moved your html code to the top.

i would also imagine you could move your css to the css tab and your javascript to the javascript tab to make the html a little bit easier to read.

Answer 3

when i moved you html to the top, all your questioned showed. i then got an error message when i clicked on the submit button. when i moved the submitbut function i got another error message and kind of gave up.

second error message.
ReferenceError: Can't find variable: showResults at Line: -37
