That is exactly correct.

Perhaps it is time to re-state your problem. I thought you were dealing
with coloring problems (i.e. problems with the controls). Now you say you
have linking problems also (i.e. problems with you data linkages).

For a lookup you must set the KeySource property and some others
besides; and the format of KeyLinks is **different** for this type of
relationship. If you have the GSG (Getting Started Guide), please look
closely at the steps for the data linkages.
