I have a table that looks something like this:

```
1 1 - - 2
1 - 1 - -
- - - 2 2
1 2 - - -

```

The dashes are missing values.

What I want to do is highlight all rows where the nonmissing values are different. In the above fake table, rows 1 & 4 would be highlighted because they have 1s and 2s both. In contrast, row 2 only has 1s and row 3 only has 2s so it wouldn't be highlighted.

I figure I'm supposed to use a custom formula for conditional formatting, but I can't figure out the exact query. Can anyone help me out there?
