[ic] UserDB custom field access?

[Himem Inc]

I added a field to the userdb, and would like to be able to access this 
in a webpage.  I have tried various configurations of the [userdb] and 
[data] tags, but cant seem to get any data returned.

[data session contacted]
[data table=userdb column=contacted username="[data session username]"]
[data table=userdb column=contacted key="[data session username]"]

Any suggestions?
