I have a dropdown box that is linked to a cell where a date is put that is
used for other things. The drop down box is filling itself from a range,
which contains a sequential list of dates. I have verified that the dates
are indeed dates and not text values. However, whenever I select a date
using the drop down list, the link cell reverts to a serial format. I have
tried to reformat the cell to be mm/dd/yyyy manually but without any success.

Should be a simple reason but I am stumped here.
