From what I can make of the above description, you're possibly trying to use the IB_LookupCombo for the wrong kind of relationship. What do you mean when you say "..don't show when the IBL_LookupCombo is displayed on the form..." ?

GridLinks is a property of the control, specifically a property of the drop-down list part of the control, which is an IB_Grid. In the case of this control, it enables you to have multiple fields in the list.

Data controls are set-driven. The datalinking between the set and the control is by way of the IB_Datasource. The only way you could have fields from multiple tables would be if the set were from multiple tables, i.e., a joined set or one with expression fields derived from subqueries.

You can't have multiple fields in the field part of the control, if this is what you meant. That's not how lookup controls work. The field part contains a unique key or, more usually in practice, the descriptive text associated with a unique key.

It's not at all clear to me what you are trying to do here....
