Adding up dates selected in datepicker

[bartkean]

I am very new to VBA and would really appreciate any help that someone could offer -

I need to be able to select multiple dates in datepicker, then, just by the sum of dates selected, populate the cell. Simply put, if I select 6 different dates, then the number 6 would be displayed in the cell by itself.

Also, if possible, the datepicker needs to retain the dates previously selected. So if I open that cell again, I can still see the dates that I selected previously.

And the option to deselect dates, as well, needs to be available.

I have searched various places for an answer, but I have not located one.

Thanks,
Bart
