It's Friday and I'm getting nowhere looking through the forum(s). So, here's hoping...?

I've got 3 rasters that need to be mangled through the following sum using the Raster Calculator:

("mean_curv" x "mean_curv") - (("plan"-"prof") x ("plan"-"prof") x 0.5) = Output Raster

I'm sure I used to do this using the old VB, but my head hurts now. :(

Any help would be much appreciated.
