ExecuteError: ERROR 999999: Error executing function.

i got the this error message.
what's wrong to me?

why is your cellsize in quotes?

why is your cellsize in quotes?

My projection is GCS, so my cell size is quotes.. ^^

[LEEjongseok]

it is my attribut table in the shape file.

and, new code is here.

help me...TT

Oh, now I think I see the problem, although you may have more than one problem - I'll tell you what I think is the most likely candidate 1st.  Is it true that you are listing point shapefiles for the input in the loop (even if it is just one iteration)?

The thing is, if a shp, the file has of course a .shp extension - you're feeding this into the output name.  Your output location was specified as "C:/py2/result" and to that you're joining the input filename which is going to balk at the .shp extension...so if you strip that off, I think you may be okay --- you can do that something like the following, replacing your outRaster2 variable line in the loop:

outRaster2 = os.path.join(OutputFolder2, os.path.splitext(filename2)[0])


(that's GRID raster format; for jpg, etc, add the necessary supported file format extension, as in):

outRaster2 = os.path.join(OutputFolder2, os.path.splitext(filename2)[0] + '.jpg')


Sorry didn't see that sooner!
Two other things I question is the 'NONE' parameter value, maybe should be an empty string '', and I agree with the cell size as suggested before this post - should probably be numeric.  If you run into further problems, maybe you should try leaving off some of these optional parameters to make sure it runs in minimal (or default) fashion at 1st.  Then continue testing adding in your 'fine tuning' params to get just the output you desire.

Hope that helps.
