I have an Excel list and for one "field" (column) I want to create a
dropdown picklist. The pick list choices are 1, 2, 1/2. These refer
to clinical trial phases so the items in the list will be designated as
Phase 1, Phase 2 or Phase 1/2 (both phases)

When I create my pick list as 1, 2, 1/2 in the validation menu it
creates a picklist whose choices are 1, 2, and 2-Jan. Preceeding the
picklist values with a single quote will prevent the 1/2 from showing
up in the list as 2-Jan but then when it is chosen in the list the
field shows an type error in that cell.

Can anyone advise me of a work-around?
