change h3 to h4

[SCDL]

Hello all...

I'm trying to match my zencart shop

http://sewcrazydoglady.com/shop

to my website (wordpress)

http://sewcrazydoglady.com

But I'm having trouble with some of the sidebox headers. I have this in my stylesheet

h3.leftBoxHeading, h3.leftBoxHeading a (line 511)

{

background-image: url(../images/paw.gif);

background-repeat: no-repeat;
}

but it's resulting in TWO little hearts in a few of my sideboxes.. All I can figure is it's nested divs. I was thinking maybe it would be easiest to change one of the h3's to h4's..

unless someone can advise as to how to fix this in CSS

Thanks!
