Replace in File

[lherz]

First, please excuse my regex ingorance, but I am trying to use the regex function in the replace in file step to update the third element of a build number on a line within a text file. I have been able to get the match that I need, but I am looking for a way to replace a number with that number +1, and am having no muck.

Am I barking up the wrong tree here or am I just not getting the concept?

Any assistance would be greatly appreciated.
