CSS help – formating an h2, can't change color

So I have this html:

<li id=linkcat-7 class=linkcat><h2>Professional Organizations</h2>

I have this css on line 544 (I know this has an affect on the html because I can alter the size of the .linkcat h2 by altering it here):

.linkcat h2 {color: #3F6; margin: 0; padding: 0px; line-height:none; font-size:14px;}

And this on line 499 (I know THIS is controling the color of my html above, because when I change the color here, it changes it for that html output):

#content h2,
#content h3,
#content h4,
#content h5,
#content h6 {
	color: #000;
	line-height: 1.5em;
	margin: 0 0 20px 0;
}

What am I missing? ??
