"Merge into" wierdness

I'm doing a merge into command where I query a table that holds multiple
scenario items in it.
The objective is to transfer the selected scenario items from the "source
scenario" to the "destination scenario".
Some of those records might have been transferred before, in which case the
non-key values are to be updated from the source. If they haven't been
transferred before, they get inserted.
The statement worked like a charm.
Then I needed to add another column to the table, and that column needed to be
added to the ON clause.
I added it and the statement fails - the error message says the column doesn't
exist in the table.
"Oracle Error Code = 904
ORA-00904: "L_TO"."UNITTYPEID": invalid identifier "
If I remove the column name from the ON clause, the statement runs.
I'm flat-out certain I didn't mis-spell the column name or its prefix.
(I cut-and-pasted the column name from the source select statement and the
prefix from other destination columns, plus I've had another set of eyes
double-check.) (You would make be very happy if I'm wrong...)
The source select statement in the merge command can clearly find the column,
so it's not like I'm pointing to the wrong version of the table or something...
I've got 7 phrases in the ON clause, if that makes a difference.
Any clues? I don't have access to meta-link where I'm at.

Here's the table and statement, somewhat simplified. Hopefully it will remain
readable.
