The formulas in the gem bonuses for the trinkets in the lookup sheet are giving #N/A because the vlookup is referencing the wrong column. It should be 23 not 21. (I was using Volatile Alchemist Stone)
Here are some corrections
'Fury Calculation'!S135
=VLOOKUP(VLOOKUP(P124,Trinket2Lookup,23,0),SocketBonusLookup,15,0)
'Fury Calculation'!S136
=IF(AND(P135=TRUE,Q135=TRUE),VLOOKUP(VLOOKUP(P124,Trinket2Lookup,23,0),SocketBonusLookup,VLOOKUP(S135,GemLookupVlookupNameCodes,2,0),0),0)
'Fury Calculation'!S121
=VLOOKUP(VLOOKUP(P124,Trinket2Lookup,23,0),SocketBonusLookup,15,0)
'Fury Calculation'!S122
=IF(AND(P135=TRUE,Q135=TRUE),VLOOKUP(VLOOKUP(P124,Trinket2Lookup,23,0),SocketBonusLookup,VLOOKUP(S135,GemLookupVlookupNameCodes,2,0),0),0)
