Nintex 2010 Lookup function requires use of ParseLookup – Really?

What should have been:

=lookup(“scmProjects”,”Project”,(brad),”Legal Entity”)

ended up as:

=parseLookup(lookup(“scmProjects”,”Project”,parseLookup(brad),”Legal Entity”))

Parameters are: list name, lookup key, named control containing key ( in this example “brad” ), returned value.

So where was this documented? Only with the assistance of an experienced developer was this resolved.
