Help with a isnumber, iferror, search formula

Hi can someone help me with a formula please?.....

I want to have 0,1 or 2 in column B depending on text in column A

Column A Column B
Macks 1
Macks/Baxter 2
CFL 0
CFL/Langmead 1

So if the cell doesn't contain CFL and it doesn't contain a "/" then its 1
If it doesn't contain CFL and it does contain a "/" its 2
If its CFL only its 0
it it contains CFl and it contains a "/" its 1

I have tried lots of different ways and it works almost except it wont work on either the CFL/ or the MACKS/BAXTER

this is the formula I have at the moment and have stopped at

Formula:

Any help on this would be very appreciated as ive been spending the last hour or so trying to get his right....

Thanks
