Canīt finish Active X Combo box - drop down

[Washington]

Can somebody please help me finish a drop down menu using Active X?

I know how to turn the autocomplete on and off but I donīt have a clue where I configure the data range or the cells to display the list when the combo box is clicked.

I am assuming that this is done in the Edit mode at "linkedCell" and LisfFillRange ... yet I canīt get this to work.

Could you please download the attachment and finish the dropdown for me so I can look at how it is done?

Thank you :-)
