I want to add an item to an activeX combobox that is located on a worksheet. Note this is not the combbox from the forms toolbar, and its not the combobox inside of userforms, its the control toolbox combobox. I'm getting an object doesn't support this property error when I try the following: Sub PopulateList() Worksheets("Sheet1").ComboBox1.Items.Add ("Item1") End Sub How do I add an item to this combobox? I don't want to use the ListFillRange property b/c I will be putting this inside of a loop. Thanks in advance!
