Is there a way to create a drop down list in a cell which can be added
to?  Excel 2007
Currently have a worksheet with a list in cells z50>z55 with entries
Then selected g5 to 50 and data validate > list > named range z50>55
Works well except when there is a change to one of the figures in the
Other than picking from this list no other entry can be made in g 5 >
So would like to be able to add other numbers to the list and have it
Is this possible?
