Code needed to restrict width of Google search box in SMF ads please.

[RUA]

I am asking any member who knows how to do this please.........

My ad mod works generally fine. At the bottom of the forum I have a Paypal donate button and I wanted to put a Google search box in there as well, so I did it and the Google box stretches the entire width of the screen. 

You can see here at the bottom of the page. I want it centered, and about 600 wide. Can someone tell me the code I need to put each side of the Google script in order that I can do this please?

I fixed it. In case anyone else needs this, put the Google code in a table, I got the info from here.
