I've tried googling this, but to no avail, so maybe you guys can help me out. I have a table of numbers + names, and I need to output a table of percentage differences between these numbers.

Looks like this UNOXpGA.jpg

One output table needs to include which numbers have a difference of less than 10%, the other -- more than 30%. Each percentage needs to include which names were compared.

How do I do this?
