Invalid Pattern Match Value for Replacing Spaces

[sleake]

I found some examples of replacing extra spaces, but I can't get this one to work. It's supposed to replace multiple spaces before a number with a single space. The error I'm getting is: The Find What text contains a pattern match valye that is not valid.



Find What: ( {2-9})([1-9]) -- space between ( {
Replace with: \2 -- space before \2
