I just downloaded the data from this public Fusion Tables http://tables.googlelabs.com/DataSour...
When trying to upload it to Maker I get an error. I think this will be a very typical scenario.
Sorry this isn't working correctly. I tried some other Fusion tables and they parsed without issue. I've logged the issue with our engineers and I'll let you know when we have a resolution.
I opened the file in OpenOffice and resaved it and then was able to upload it without issue, it is available here: http://geocommons.com/overlays/72191
Sorry about that,
