Excel 2007 :: Choose Date From A Range Of Dates In Column On Sheet

Excel 2007 Q: I have a combo box (ActivX) that I want to be able to choose a a date from a range of dates in column A on sheet 'Working Copy'. I want a cell to update with the number/position of the date when the date is chosen i.e. the first date in the range yields 1 the second date yields 2 and so on. I also want the date to be displayed in dd-mmm-yyyy format. I am able to get the cell to give the correct position of the date but the date reverts to five digit number in combo box. I can change the code to return the correct date in the combo box when the date is chosen but then the cell just returns 0.

How can I make it so that the combo box returns the correct date and the cell updates with the position instead of jsut one or the other?

Here is the code I am using

Private Sub ComboBox1_Change()
ComboBox1.Value = Format(ComboBox1.Text, "dd-mmm-yyyy")
End Sub
or
Private Sub ComboBox1_Change()
Sheets("Working Copy").Range("G1").Value = ComboBox1.ListIndex + 1
End Sub
