Bonnie-
AddItem adds the entire row to the listbox, so once you've issued the first AddItem, the second column exists. You simply assign the value to it. IOW, you would use the

Control.List(nRow [, nCol])[ = cChar]

syntax.

THIS.AddItem('FirstOne', 1, 1)
THIS.list(this.listCount, 2 ) = '2ndColumn'

This is just an alternative to Bruce's suggestion.

>THIS.AddItem('FirstOne', 1, 1)
>THIS.AddItem('2ndColumn', 1, 2)
