Trouble executing expression in raster calculator

[LaurenRoss1]

Hi all,

I am trying to execute this expression in raster calculator:

"flowtopo" * "K_factor_100" * "C_factor_1000" * 280 * Cos((("Aspect") * (-1)) + 450) * .01745)

However, everytime I try I get error 00539: Error running expression: rcexec.

Can someone tell me where I am going wrong?

Thanks

I counted up your parens (an old trick) and didn't see any issues. I would check to make sure all of your strings map directly to raster layers in your ArcMap session. Maybe you mispelled one?
