What is your main problem?

Another thing, I would cancel your subscription with your current web-hoster because your website shouldn't be that slow unless your self-hosting.

This is the way my size option is on my site currently. (Drop down box)

I would like to change it to be like this.

I was told that this is the code I need. http://jsfiddle.net/obmerk99/FJqVA/

I'm not really a programmer, Id appreciate any advice.

Thank you!
