odd error updating - varchar

I am trying to update a table and I'm getting an odd error. I've narrowed it
down to one attribute, but can't see what the prolem is.

Anyone got any ideas?

goole=# update requests set r_chassis = 'GAJD7P26209' where r_id = 18560;
ERROR: attribute 7 has wrong type
DETAIL: Table has type character varying, but query expects character
varying.
