I am creating a drop down list based on a "Month" column in my data. ie. this
line item is associated with January, this line with March etc. The problem
is that I have several lines for each month. Is it possible to create a drop
down list that will only list each month once based upon the "Month" column
in my data?

Thanks!

Not sure if I understand you correctly, U may try this one:

to make list of unique values:
Go to: data - filter - advanced filter
Choose the area for list (source list, which consist duplicate names of
months or what)
Insert the same area to Criteria dialogue
Check box: without duplicate inputs
Choose copy elsewhere and choose the left up cell of the area where you wish
the list to be displayed (copy to).
N.B. I use localiyed version of Excel (not english), I was trying to
describe the way, however the names in the dialogue may be different for sure.
Hope it helps :-)
