Hello, I am trying to combine a few rasters together and getting the 000539 error. I checked out a few forums for solutions but could not resolve the issue. I know it has something to do with Python not being able to communicate with Arc, but I cant find the solution to my own error anywhere online. Can someone interpret the message and provide a possible solution please?
