Try changing the rowsource to "Tabla.Codigo, Nombre" with rowsourcetype of 6 instead.

>Hi all...
>I Have a form with a table in the data environment and wnat a combobox to display only two columns with only two of the table fields. I set the RowSourceType to 6 and RowSource To Tabla.Codigo and it works fine (one column), but when I try to add a second column to the combobox (ColumnCount=2, and RowSource to Tabla.Codigo, Tabla.Nombre) then an error occurs.
>I tryed with RowSourceType to 2 and RowSource to Tabla.Codigo, Tabla.Nombre but nothing...
