I want to display multi column combo box, where user selects the a/c code from parent table and child table field gets updated i.e.

Combo Box properties

RowSourceType=Alias
RowSource=GlMstView && i.e. General Ledger Master Views
Controlsource=Trans.Codefk && i.e. field in child file...

How I can display 2 columns in the Combo list i.e. GlCode, GlDesc ??

TIA...
