Re; Grouping Data?

[Jay]

As you can see from the sample below, there are multiple instances the same
month name data. What I'd like to do is some how group these into one
instance of each. The column represented here is taken on of a sheet named
"Values" column A1:A1000, which in turn is pulling the date data from off of
a sheet named "DataEntry" column B4:B3000. On the "Values" sheet I want to
only show one instance of the month name. Is this possible to have a function
pull it all together and have a date of 05/01/05 show-up as 'May-05? Yes,
that's correct 'May-05. I do not want 05/01/05 to show up in the formula bar
as a date, I want to see 'May-05 in the formula bar. Is this possible? If it
is how?
