Hey ive tried everything!!!!

I want to make just one table scrollable, not all the rest of the tables (ie, the table next to it, i dont want to affect). I have created a .css file and linked it to a page with a (.)label for the specific properties listed in the style and specified the Class=(). Someone please give me a simple way to make sure i have done this correct. SIMPLE!!!

The font properties take affect, the size properties take affect, but it wont generate the scrollbars. I have set the overflow on auto and scroll, but it repeats my background instead of generating scrollbars.

I need a simple explination on how to add a style to one table within a site, without affecting all the others.

Any help would be appreciated!!!
