user form and date & time

I have attached sheet for an inventory with a user form. I have received help from forum members for date and time pickers. I have a user form in the file with a date and time picker.

My problem is I can not find a way to access the picker while in the cells in the user form. There are 38+ places where I need the user to enter the date and time. I tried a commandbutton1 while in one of the target cells, it did not work.
