Hello, I've installed on my notebook the ArcGis 10 demo version, and I need the IDW tool to make an interpolation analysis for my G.I.S. master thesis that I've to finish as soon as possible. Unfortunately, the IDW doesn't work for any of point data I have. Only the first I manage to create. It is not specified also which kind of error it is done:

Can you help me, please?
