I'm trying to extract the task acceptor name from the task comment to be able to assign the next task to the same person. From previous posts I learned that this can be accomplished by using a regular expression to extract the name from the task comment. I've tried to do this but when I do this I don't get anything. I've tested the following two regular expressions in regexr.com on the comment result and it shows it should pull the name, however when I use it in the regular expression in Ninetex o365 I get no result. I've tried

^w++,]w+ and (^w+)(.?)(?=()

to extract the first two words since the comment field displays as 

lastname, firstname (action) 4/17/2020 10:01:58 AM - 4/17/2020 10:44:18 AM - M] :  

The collection always displays p] as the result with an item count of 0

I'm using a Regular Expresson as follows:

String: {variable: Task_Lev01A_Comment}       (this was saved in the task as a text variable from task comments)

String Operation: extract

Pattern: ^w+P,]w+

Output: Task1_Acceptor   (this is a created workflow variable of type collection)

What am I doing wrong? Does anyone have a regular expression that would work? am I missing something critical?, is there another way to do this. I've read other ways to try and get this info, but they are all way above my skillset since I cannot even tell what they are talking about.
