The following is an array formula. You must enter it with CTRL+SHIFT+ENTER
C2:IQ2 is your components
C6:IQ6 is product 3

=(SUM(NOT($C$2:$IQ$2="x")*(C6:IQ6="x"))=0)

Hi,

I have a spreadsheet that looks like that:

Components A1 A2 A3 A4 .... A250
Inventory x x x ... x

Product 1 x x ...
Product 2 x x ...
Product 3 x x ...

Basically, Product 1 & 2 could be done because all necessary components
are in
stock, but Product 3 could not be delivered because A3 component is
missing.

I would like to have a formula that determines automatically if a given
product
can be build based on the inventory.
I started with IF statements, but the formula is too long...

Thanks
