error when changing tutorial data for states to counties

[mc]

Hello,   I get the following:   "Local Concept 'county', referenced from Slice 'county_slice', could not be found."   I have changed the line:       xmlns:geo_us="http://www.google.com/publicdata/dataset/google/geo/us" to:     xmlns:geo_irl="http://www.google.com/publicdata/dataset/google/geo/irl" does this mean I should already have county data registered as a dataset before I can do this?   I attach my files

I'm now getting a similar error

"Local Concept 'population', referenced from Slice 'states_slice', could not be found."

I've checked my csv files and slice_table definitions and "population" is listed.  Were you able to fix yours?

Ok I fixed that error, had to create a specific concept for "population"
