How do I populate a combobox in a userform with the values in an Excel sheet?
Say sheet name as "Reg ALL - current".
I need to populate the value from cell AI (which is a date column).
Also I need to increment the date one day from AJ to cell BF.
Example: if AI holds value (19/06/2019) then AJ should hold (20/06/2019) and so on until BF.


AddItemmethod and aListproperty both of which can be used to assign to it. It's not at all clear what the rest of your question is talking about incrementing dates on a worksheet. Please try to improve this question..RowSourceproperty.
