First of all, you should NOT be using index-time field extractions (TRANSFORMS) unless you really know what you're doing and why. In this case one reason why your fields are not showing up could have been that you were looking at data that has already been indexed, so this field extraction had not been applied to them. However I see issues with your regex - btw putting it in an image was kind of a bad idea because if someone (like for instance, me) wanted to debug your regex they (I) have to manually write it again.
Anyhow, on to the regex: in your first group you're matching one character A to Z, followed by one or more , characters. Underscores will not be matched at all. So, the text " I,,, " would be matched, but for instance " IVADMID, " would not. Even less so with " IV_ADM_ID, ". There are a couple of other things as well but to make a long story short, this regex works better:
\((\w+),(\w+),(\w+)\)\s+VALUE\s+\((\d+),(\d+),(\d+)\)
It's always a good idea to test this stuff before applying it. I often use http://regexpal.com/ or http://gskinner.com/RegExr/ .
