excel - Enforce a rule that ensures cell groups hold unique values -
can apply rule in ms excel ensure cells c, d & e (for example) each have different value each other, row?
solved!
c1 data validation: not(c1=d1), not(c1=e1)
d1 data validation: not(d1=c1), not(d1=e1)
e1 data validation: not(e1=c1), not(e1=d1)
simpler thought :)
