Good catch, Mike.

If the controlsource is numeric and doesn't change the BoundTo property, he's getting index values instead of the actual ID number.

>Usually the control source for the combobox should be the same as recordsource of the grid. The combo box rowsource should be the lookup table (client table). Additionally, you have to be careful if your id is a numeric because by default the combo box works different with numeric values. In this case, you may need to set the BOUNDTO property to .T.
