I see where there is an option to set column length min and max.
But my needs are just a bit different.
I only want it to accept a length of 18 or 33.
Nothing more, and nothing less.
Iv tried this:
(OR(LEN(columnName1) = 18, LEN(columnName1) = 33), "Valid", "Invalid")
and, no matter what i input, it says invalid.
And also, i dont know if this will go in app formula field, or data validity>"valid if" field.
