Raster Calculator Error

Discussion created by ajm236 on May 2, 2014
I am getting an error running raster calculator that I can't figure out.

I have 2 rasters, narr_grid_Clip and sc_neg15. The first (narr...) has values ranging from 1 to 10. The second (sc...) only has data when the first is equal to 1. The calculation I am trying to run is very long, but repetitive with other layers similar to sc_neg15 that correspond to other values of narr_grid_Clip . I have trimmed it down to just the part dealing with sc_neg15, but the error remains exactly the same. I figure it will be easier to debug the small version, and then apply it to the larger one as a whole.

Here is the simplified calculation:
[INDENT]Con("narr_grid_Clip" == 1,"sc_neg15")[/INDENT]

And the error messages:

Any help would be greatly appreciated.
