As a data analyst, I want a list of registrants whose Boston Family Days IDs do not match Firebase's, so that I can manually verify eligible users who mistyped their Boston Family Days ID

Poker: 40

Done definitions:

• The Apps Script generates a new Google Sheet listing all registrants whose Boston Family Days ID entries do not match those in Firebase
• The manual includes a set of instructions so that the Data Analyst can identify and navigate to the Google Sheet in the Apps Script
