Excel 2007 : Getting Vlookup to ignore 1st "IC Prov" and return value on second "IC Prov"

Hi, I am using Vlookup, but I have a problem, I have 2 identical items within my range.

If I have as follows:
IC Prov 145.00
IC Prov 150.00

My formula is as follows:

=IF(ISNA(VLOOKUP("IC Prov   ",$I$16:$X$83,15,FALSE)),"",VLOOKUP("IC Prov   ",$I$16:$X$83,15,FALSE))

How can I modify the formula to ignore the first "IC Prov" and return the value on the second "IC Prov" without having to change the range?

Thanks
