A challenge:
I have a list that has 48 columns in each row. Each cell has a score of
1-4. I would like a "true" return if specifically and only these cells have
a 1 and others do not have a 1.
For example:
A1, b1, c1, e1, g1, h1, i1, (etc.) have to be a 1 for the line to be true
D1, f1, j1, k1, (etc.) if any or all of these are not a 1, the line is true
Basically I have 40 cells that need to be a 1 and 8 cells that at least one
has a different number.

I could write if a1=b1=c1=e1=g1 etc., but that is a very long equation.

Thank you
