How about adding a "counter" column along the left edge of your table, and using a vlookup as follows:
=VLOOKUP(MAX(A1:A13),A1:C12,3,FALSE)
where column A is your counter column and column C (3rd one over, 3 in the formula) is the value to be returned.
You could get tricky and cover yourself for changing table size by putting in more counters than you'll ever use, with the counter cells starting in A1 with a 1, and in A2 through the end of your possible table size using:
=IF(B2="","",A1+1)
Then fill to the end of your biggest possible table.
There are prettier ways to deal with your changing table size with macros, about which Mr. Excel has written extensively.
Thanks for the help. Instead of adding another column I justed set the max on the date field and it worked. Thanks again.
