Please refer attached worksheet and advise a formula to lookup and then
do a calculation and adding IS ERROR to it.

if you calculate the price per unit in column F it is much easier.
In F2:
=B2/(C2-D2)*(E2="RETAIL")

In B17 you need:

=IFERROR((VLOOKUP(A17,$A$1:$E$10,2,0)/(VLOOKUP(A17,$A$1:$E$10,3,0)-VLOOKUP(A17,$A$1:$E$10,4,0)))*(VLOOKUP(A17,$A$1:$E $10,5,0)="RETAIL"),"")
