Probbably something simple I am missing. . .

A form with two combo boxes (set to drop down list style) and a grid: the resulting selection of the first combo box, runs a SQL select to fill the snd combo, box. The result of the 2nd combo box runs an SQL to fill the grid.

The two selects take time, so I don't want to run them on the INTERACTIVE.CHANGE (because they would run when the user paused to choose from the list). I need an event that fires when a new item is selected from drop down list. When the user selects an item from the list, I want to run the sql and advance focus to the next control.

What am I missing?
