I am using a LOOKUP and do not understand what is going on. In cell L18 I am
using the following formula:

=LOOKUP($L16:$O16,INDEX($L$4:M$13,0,0))

When I highlight the formula and hit F9 I get:

{100,105,110,115}

Which is what I want. However if I increase the range in the formula to
column P:

=LOOKUP($L16:$P16,INDEX($L$4:M$13,0,0))

When I highlight and hit F9 I get:

{100,105,110,115,0.50}

Why does this not work? The last value should be 120. The goal here being
that I want to use a lookup variable which is a range and search for it in
another range and return a particual column of adjacent values.

Note the reason I am doing this is that I putting the Lookup into a
SUMPRODUCT formula.
