Here is an error message I receive when I attempt to run a custom toolbox:

ERROR 010029: Unable to create the raster C:\Temp\SAMPLE_ROUTING_PROJECT\analysis\alternate_corridors\intermediare\proximity_raw.  Distance mapping is failed.
Error in executing grid expression
Failed to execute (Straight-line Distance Calculation for Building Proximity).

Any suggestions as the cause of not being able to create  the raster and any solution suggestions?
