Hi all,

I'm trying to use Map Algebra/Raster Calculator on some tiff files, all of which are identical in properties but for cell values.  I keep getting an unidentified, unexpected error.  Am I wrong and tiff files don't work in raster calculator?  I converted 2 of them to GRID and tried a simple operation and no luck.  I tried an operation on just one, to make sure it really is the files themselves and not my expression.  Any ideas?  What do I need to do to make them work?  They're currently tiff continuous 32-bit floating point rasters.

Thank you!
