1. How do I make the fields show up in the combo?

Combobox.RowSourceType = 6 && Fields
Combobox.RowSource = "myview.Field1, Field2"
Combobox.ColumnCount = 2
Combobox.ColumnWidths = "100,100"

You'll need to play around with the numbers in ColumnWidths to get it just right.

2. How do I address the value in the 1st field in my search code?

Combobox.BoundColumn = 1
