Lookup function

[StacyM]

I have tried and tried to figure this out by looking at past discussions, but
I keep missing something. I have a table like this that is linked to a table
on the internet, so I can't change the format of the table. The Month column
is a custom formatted cell showing the year and month for the settling price.
I need to make a cell in another sheet that finds the correct month/year and
gives me the settle price. Because the table is liked to one on the
internet, the month column is changing at least once a month so I need a
lookup function to keep finding the values.
Month Settle
9-Aug 15.04
9-Sept 15.67
10-Jan 16.71
10-Feb 16.82
11-Jan 16.23
11-Feb 17.85
=LOOKUP("9-Aug",Sheet1!A8:A31,Sheet1!G8:G31)
This function gives me a #N/A message. I think it is because excel sees
9-Aug as 8/9/2009. This is fine, but when I try
=LOOKUP(8/9/2009,Sheet1!A8:A31,Sheet1!G8:G31) I still get #N/A.
It seems like it should be really easy to do, I just can't seem to get the
function correct. I have also tried the VLookup function, but I have the
same problems. Thanks for your help and my Excel skills are fairly basic so
I apologize if this seems very elementary.

does the cell also have a time in it, like 8/9/2009 5:45, if you are just
looking for a month, insert a column- =month(a1) or whatever and lookup that.

Normally Aug-9 would be
8/1/2009
not
8/9/2009
is yours any date in august or is it the first of the month. If it is any
date then it gets more difficult.

Here is first of the month...

=VLOOKUP(DATEVALUE("10/1/2009"), A1:B10, 2, FALSE)

This works! All I had to change was the DATEVALUE part. Thanks so much for
your help and quick replies. Have a great day!
