Cake Calculator!

I've noticed a lot of people on the cakecentral.com forums asking about cake sizes and serving amounts.  I've been using the Wilton charts:

Earlene has another popular chart:

But wouldn't it be nice if there was a chart that could do the work for us?  It's been too long since I've dabbled in web page programming.  Here's what I got so far.  It's ugly, but functional.  It's using the Wilton chart data for 2" pans.

It's a work in progress, but I have high hopes that I can incorporate some more functionality in my spare time.  And maybe make it pretty.  Don't expect too much ... I'm a programmer, not a graphic artist.
