I am trying to use the following index function. Seems to me like it is ok,
but when I type this into the cell I do not get a result, I simply see the
formula (I do not have the view formula option selected). I am using Excel
2007.

=INDEX(Results!$D$2:$D$21,MATCH($B3,Results!$A$2:$ A$21,0))

I have tried to make this an array formula, but that does not work. When I
select Ctrl+Select+Enter nothing happens.

What I am trying to do is find a match to cell B3 in one worksheet to an
entry in column A from worksheet "Results" spreadsheet. I then want the
corresponding entry in column D from the "Results" spreadsheet to be my
answer.

I should also note that the entries in column D are text and not number or
formula entries.

TIA
