Been trying (without success) to insert a row of custom data into an email triggered out of SFDC that picks up a DE from Exact Target.
Read lots and lots of documentation and tested many hours but no dice.
Could it look like this: %%=Lookup("303030","PURL","Subscriber Key",Subscriber Key)=%%
Where 303030 equals the external key of the non-sendable data extension PURL is the field I want to display Subscriber Key is the loaded primary piece of data in the DE Subscriber Key is coming over from the SFDC ET plug-in
Is there more? What am I missing?
