Hi, I wonder if anyone could help with this, preferably
programmatically. I am a newbie to Filters so step by step would be
nice....

I have two columns (J and K), in which the same row may show the same
or different (text) value, depending on complex calcs elsewhere in the
sheet. J and K already have a manual autofilter set up. The rows run
from J2 to K633, with the first row showing the category name.

What I want is, a programmed filter which shows only those rows where
the column J and K values are different....

Preferably in code, so I can attach it to a button, or so I could get
it run run automatically when calculations change.....

Sounds simple enough, but hours of searching the web have drawn a
blank...

Thanks.
