Hi all,

I have a peculiar problem with a function. I am using Excel 2007. I am
working with about 57,000 records. I must match the rate of an audio call
based on two conditions. I am using the following formula against a list
that is sorted in ascending order:
=INDEX('Rate Table'!$E$34:$H$98,MATCH('Veri vs Interc Clean Data 2010
'!G597,Entity,0),MATCH('Veri vs Interc Clean Data 2010 '!E597,'Rate
Table'!$E$33:$H$33,0))

I can find a match for all but 600 or so records. There is a match, without
a doubt for the other 600.

I have made sure that the text the lookup is based on is clean...no trailing
or leading spaces. I have even cleared the cells and retyped the data just
as it is in the lookup table. No matter how many times, I write it or how I
modify the function, those records return 0. I have also updated Excel, ran
diagnostics, copied the data to a new workbook, opened and repaired...I just
do not know what else to try. Of course, the report is due Friday morning.
Any help would be appreciated.
