Different values in renaming a file

Hello! This is my first post here 
I receive payment orders from Google Ads in which there are different amounts of payments.
For example: 6,000 or 12,000
I want one of these money amount values ββ(6,000 or 12,000) to be inserted in the file name. I made a rule like this https://d.pr/i/4O4GET
Unfortunately, it works with errors. How to create a single rule that would substitute different values ββin the file name? I understand that you can create two rules with renaming, but it seems to me inconvenient.
P.S. Sorry for my English. Wrote this post using Google Translate.
