Okay I still don't get what you want.

I don't find a date time picker.

I see you have a multi tab form, there's a tab named Date with a combo box for picking the date. When I run the form and hit finish it puts the date chosen in column A of the Data Log sheet.

This line of code is what is putting the date on the sheet:

ThisWorkbook.Sheets("DATA LOG").Cells(nr, 1) = Me.cmbDate
Where is the date time picker and what is the issue with it?
