Hi,

Need some assistance trying to complete a multi-lookup formula (and avoiding the SUMPRODUCT function (it's slow and the dataset will be of large size)).

I've attached some sample data for reference. The columns may change position so using the VLOOKUP function with fixed columns won't suffice.

The requirement is the following;

Look up a certain project - let's use 'A3' (Project A)

If the project exists, then lookup 'D2' (Stage 3) intersection/corresponding value to see if the value is equal to 'Authorised'

If the project exists then lookup 'E2' (Artefact #1) intersection/corresponding value to see if the value is equal to 'Complete'

If all of the above, the test is satisfied so output the number '1', if false, output '0'

Thanks
