Larger Marquee, Marquee not large enough Options

[DarkMouth]

[FONT=Geneva]Okay
OOOOn my myspace which is http://myspace.com/bluemouth under my movies area the marquee i have is acting the way i want, but the problem is when i go veiw my profile its all small and u can only veiw like half of a movie poster at a time
the code im using is:
<marquee behavior="alternate"><marquee width="75%"> URL HERE </marquee></marquee>

Now i experimented with the marquee width typing all numbers and even add a spot for height. . . Still nothing. . . Well at least not what im looking for

So if u got any advice
PLEASE HELP
ive been tryna figure this thing out for a while
