Lookup function gives wrong values occasionally

I wanted to use the lookup function to get a numerical value with
reference to my lookup value, which is a text entry. For the setup of
my spread sheet, I could not use vlookup or hlookup. This lookup
function gave me some correct values, but mostly incorrect ones. The
following is my command:

=LOOKUP(DL2,$AV2:$BL2,$BM2:$CC2)

I checked the lookup value and the lookup vector... they are exactly
the same without spacing or spelling errors. Since I got some correct
values and some incorrect ones, I suspected that the lookup function
does not work for text entry. Am I right? Is there any way that I can
fix the problem? Please advice.

Thanks.

LOOKUP requires the values to be is ascending sequence otherwise you will not
(always) get the correct results. Is your data sorted in ascending sequence?

Thanks, I don't know that the values have to be ascending order. My
data is not in ascending order and it is almost impossible to set it up
this way (otherwise I don't have to do the lookup thing!) Anyway, good
to know more about the lookup function and thanks again.
