Having a tough time with ExactTarget's documentation. The example below from their docs works just fine, but I'm having trouble setting the var Json to an actual JSON feed. What am I missing?
%%[ var @Json set @Json = ' [{"emailaddress":"john@example.com","Region":"West","State":"California","City":"San Francisco"},
{"emailaddress":"carla@example.com","Region":"Central","State":"Indiana","City":"Indianapolis"}]' ]%%
{{.datasource JSONVar type=variable maxRows = 20}}
{{.data}}
{ "target" : "@Json" }
{{/data}}
Email Address: {{emailaddress}}
Region: {{region}}
State: {{STATE}}
City: {{JSONVar.City}}
{{/datasource}}
