Having problems Options

[dsmith530]

Hi, I'm having trouble with a site I'm tying to build. The problem is this:
if you go to: http://megansmetalworks.com/home.html
in safari the top frame/row shows up exactly the height it should be... but in FireFox it takes up about half the page and I can't figure out how to fix it.

The code is as follows: <frameset rows="70, 20% framespacing="0" frameborder="0">


It should be 70 pixels tall in both browsers but it's not, and I can't figure out why. I think I'm the one making the error.

Can somebody please help me figure out what I'm doing wrong?

Thanks.
