In column D I have a drop down list, for which the choices are from a named
reference in another sheet. In column H, I have a VLOOKUP formula that takes
the value in the column D drop down list, and returns a value based on the
selection. I have six choices in the drop down list, and it works fine for
five of the six. For the remaining one, it returns #N/A.

Does anyone have an idea why it would do that for only one of the six
options? The VLOOKUP in column H uses the same named reference that the drop
down list in column D uses.
