I have the following statement on an excel spreadsheet. Please help me to
convert this to either a macro or vba code, the latter preferably.

=IF($A2-(VLOOKUP($A2,'LII 200 raw
data'!$A2:$D$65000,1))<1,IF(ISERROR(VLOOKUP($A2,'L II 200 raw
data'!$A2:$D$65000,4)),NA(),VLOOKUP($A2,'LII 200 raw
data'!$A2:$D$65000,4)),NA())

Thanks
Faz
