I'm a graphic design student, so this isn't my forte.
I'm trying to use the trial version of ArcInfo for the Interpolation feature so i don't have to work with GRASS. I've had no issues with the installation. However when I try to use the topo to raster by file < Interpolation < Spatial Analyst Tools I get an error. (see first picture)
however I know it's been installed correctly and ArcGIS Administrator also verifies that no issues should be occurring. (see second image.)
Any ideas as to what could be causing this?
