I need to combine the following
=IF(B2="SUSP","Suspended",A2) and =VLOOKUP(A2,Lookup!AB:AC,2,0)
explanation: If SUSP isn't found in cell B2 then match value from column AB in 'lookup' tab and then return the value from AC in the 'lookup' tab.
Excel allows the "Nesting" of formula, so just put the VLOOKUP in the False position. That way when it does not equal "SUSP" it will run the VLOOKUP:
=IF(B2="SUSP","Suspended",VLOOKUP(A2,Lookup!AB:AC,2,0))
If B2
does eqaul "SUSP" the IF will not even run the VLOOKUP.
