'hello,

can someone explain in plain English what this formula is actually
saying:

=IF(C32="FOB",(B28:C28/'Board Pricing and
conversion'!B19)-B28,(B28/'Board Pricing and conversion'!B20)-B28)

I understand the C32="FOB", but the rest I don't. I know it is
referencing another spreadsheet but don't know what it is looking at??

Thanks
