I'm trying to modify the css stylesheet that's used by the Future Zen template.

Specific problem I'm having is in trying to modify the attributes for the .productlisting-odd and .productlisting-even id's. These are part of the table html for a generated product list. I've added these lines like these to the stylesheet:

.productListing-odd {
background-color: #aaaaaa;
margin-bottom: 10px;
}

Problem is that these lines appear to have no effect.

A similar table used in the shopping cart has id's of .roweven and .rowodd. Similar specifications in the stylesheet seem to modify attributes in that table just fine.

I'm a newbie to css. Can someone tell me what I'm doing wrong?
