I'm a student at Meade Senior High School working to become a S.T.A.R.S. Certified Geospatial Technician and I have a problem. Im working in the Extended Tools in Surface Analysis book. Im trying to create a network dataset for one of the enrichment lessons, but every time I try it pops up with the message 'Could not create network dataset. The table was not found'. I was wondering if anybody could help me understand what this means and how to fix it. Thanks.
