Need multiple columns in subcategories

Go here and you will see my issue.
http://spectechind.com/store/index.php?main_page=index&cPath=659_662

I need to learn how to format these type of pages. For example, the most important change is: needing at least two columns to shrink page size and easily see all categories without scrolling.

I would also like to know how to center the main image (BW CONTROLS image at top)

Thanks.

I will bet that you are missing a float: left; for that section in your stylesheet

i don't know what that means

It means that the part in red below, which is in the stock Zencart stylesheet, is missing from yours.

#logo, .centerBoxContents, .specialsListBoxContents, .categoryListBoxContents, .centerBoxContentsAlsoPurch, .attribImg {
margin: 0em;
text-align: center;
padding-top: 0px;
float:left;
}

Add this to your stylesheet to center the category image.

.categoryImg {text-align:center;}

Perfect! Thanks for walking me through this.
