HTML problem? Google Maps?

Ok so I've modified the size of google maps in the past on websites, but there is something in the template I'm using that is restricting it to standard size. I change the dimensions in the code but nothing changes on the actual site. I've been trying to get this for awhile. This leads me to believe that some file is restricting the size of the map locally? Any idea where I should look?
THANKS. There was a CSS sidebar where I could edit the size. It worked. Thanks :D I will give you best answer when I can.
