I am trying to create a IF formula to return certain information:

If B2=COMERCIAL FINANCE

I want it to return certain numbers like

if b2=comercial finance then return 24567
if comercial finance is not selected I want it to be blank

There will be a list to choose from like
COMERCIAL FINANCE=2345
CONSUMER & INDUSTRIAL=3455
CONSUMER HOME SERVICES=4579

And so forth
