I have a workbook that is used for scheduling deliveries.

Sheet 1 is a "Control Panel" which among other things will pop up an entry form for "New Deliveries".
Sheet 2 is set up as a list which receives the data from the userform.

This all works as desired presently, but I want to write the data from the userform to a separate sheet by month based on the delivery date entered on the form.

The form has a permanently visible calendar which when clicked writes the selected date to a text box right below the calendar (as mm/dd/yy).

How can I pull the month only from the text box and use it to determine which of the monthly sheets will be activated for writing the data from the form?
