Hey guys. I'm on heatmap theme right now and it's working great, just one issue. I want to test my ad placement and want to put the 336X280 adsense block before my content, below the title. Heatmap has the widget for this but the problem is that I can't center it. The ad is always aligning to the left. I've tried doing these:

<center> ADSENSE CODE </center>
<div align="center"> ADSENSE CODE </div>

...but both didn't work. There has to be a simple trick to this that I'm missing. Calling all heatmap theme pros!
