GB IDX_GLUC=GEN_GLUCOSE. GEN_GLUCOSE is a generator that I created.

GB IDX_GLUC, which was not in my select statement. I have added it
and now the query is editable.

GB I still have a problem understanding how to use a TIB_LookupCombo
in a grid. I have been trying to follow the examples in the GSG but
it doesn't seem to work for me. I have 2 LUCombos that work fine if
on the form but when dropped on the grid they don't work/are not
visible. What I am trying to do is: In my glucose table a field
called "Finger" is an integer. In my "Finger" table the PK is an
integer and the glucose table matches to that. If the user changes
the finger in the LUCombo the number in glucose.finger should change.

Thanks,
Gerald S. Brown
