Populate combobox with names list

Hi all

I have list of names in A4:A12 and combox21 in the excel.

I want to poupulate these names in combobox21.

if the combobox is in userfor i would use
"private sub userform_initialize"
combobox21.additem.............
but if the combobox is in the sheet how do I use?

Could anyone help me to do so??

If it's an activeX box, right click, select properties and put the range in the listfillrange box

Dear Protonleah
it is an activeX control box in worksheet.
