Possibly

Private Sub Combobox1_Click()
if Combobox1.ListIndex < -1 then
Worksheets(Combobox1.Value).Select
end if
End Sub
This assumes the text in the combobox is the name of the sheet.

I want to change the worksheet in Excel by choosing it in a combo-box that
displays 18 diferent options, and each one of these options displayed in
the
combo-box, corresponds to a diferent worksheet, is it possible?
