Hello all,

I’m trying to figure out a clean way of writing a formula for a Lookup table that can hold up to 4 variables at any time (A,B,C,D).

Based on these variables, I want the formula output the following:

IF(Lookup contains: “A or B or C or A,B or A,B,C” - in any given order), output “Inhouse”, but if D is also present, still output “Inhouse”. If only D is present, then output “Foreign”.

Is there a clean way to write this?

Thanks so much in advance!
