I am new and javescript. I am having a few problems with this page of a site i am helping a friend make.

It will not work at all IE 8 debugger says 'null' is null or not an object and higlights

Code:

var news = selectnews.options (selectnews.selectedIndex).InnerHTML

I have no idea what this means.

and ever time I click submit it tries to load a page that dose not exist and i am not sure why.

Code:
