I'm a web designer. First up, what browser are you using? If you don't know how to figure this out, open up your web browser (if you're reading this, you're in your web browser). Click 'Help'. Now you'll see something like 'About IE' or 'About Firefox'. Click on that and you'll see a dialog box that tells you what version you're using.
Write that down. Come back here and post it. We'll go from there, ok?
