I am trying to use a technique to update fields with some preface information. That is that I've come up with a way to include the Updated by and Updated on ahead of the information being added to the text field. EXAMPLE:    Bob Moalli On 2/2/2021 updated the NPR from 123456 to 345678.

123456 to 345678 are coming from fields OldNPR__c to NewNPR__c

I'm being asked to present these two fields as currency EXAMPLE

Bob Moalli On 2/2/2021 updated the NPR from $123,456 to $345,678.

I'm looking for any ideas on a solution to make this conversion. Any thoughts greatly appreciated.

Thanks Bob.
