Hi- First time poster here-

I am trying to figure out a formula that will allow me to compare the
contents of cells within a range and let me know if there is a value that is
not the same as the others. For example:
Columns a,b,c,d,e and f and say "Joe"- this result is acceptable
Columns a,b & c all say "joe" and d,e,&f all say "Mary"- this result is
unacceptable

I want a formula or function that will tell me this wihout me having to
visually scan the data to determine this.

Any assistance here would be greatly appreciated.

Thanks in advance
