Error when using 2-dimensional lookup (Vlookup with Match) - please help

[d61660]

Hello,

I am struggling / pulling my hair out with the method of 2-dimensional lookup (Vlookup and Match)

I have attached, the excel file I am using. I just can't seem to get the formula in G6 right. Could someone possibly take a look and show me where I'm going wrong?

Many thanks

=VLOOKUP(G4,'Corrosion Rates'!$A$3:$G$8,MATCH(G5,'Corrosion Rates'!B3:G3,0)+1,0)
