To ensure a smooth substitution process, please follow these steps carefully:

1. Existing EntryNinja Account Requirement:
For successful member substitutions, the individual being added must already have an existing EntryNinja account. If they don't have one, you can invite them to create an account by using this link: []( Once they have been invited and created an account, you will be able to complete the substitution process.

2. Accurate ID Number/Email Address:
It is crucial to double-check and accurately enter the ID number or email address of the person being added or substituted. Our system relies on this information to recognize the individual correctly, allowing either the substitution or addition to take place.

If you encounter any errors during this process, please review the details entered for accuracy. Even a small discrepancy can prevent the system from recognizing the member.
