REGX Match and Addition Formula

[harinder1301]

Heelo everyone,

I would like to get assistance in writing a reg ex formula . When the match occurs , i want to pick the value from field  S and add it.

I have created a formula to count the comma separated values . But 

REGEX_CountMatches([A], ",") + 1 

But I want to add the values if the count is greater than 2.

Desired output is in Column B. Please see attached file.

Many Thanks

Harinder

You don't actually need RegEx for this, see attached workflow.
