Excel 2002 and VBA

Hi, when I was using Excel 2000 I was able to change the name ofcontrols (like combobox and button) by right-clicking on them andchoosing "Properties"... But in Excel 2002, this option is no longerthere ! And I always get an error "Object required" when I dosomething like that:Private Sub Button1_Click() DropDown2.AddItem "Test" End SubIt's like the "DropDown2" object doesn't exists but how can I changehis name ?Thank you.
