Hi!
Hello
I have a problem with this expression in the raster map algebra calculator for Arcgis 10. The error tells me that are not valid values ??????of the expression of truth. This expression arcgis 9.3.1 worked correctly.

Con("%slope_layer%" <= 20 , 0 , "%slope_layer%" > 20  & "%slope_layer%" <= 45 , 1 , "%slope_layer%" >= 45 , 2)

Do you have any idea?
Thank you.
Mary
