Thanks for getting back with the Community, criclacrosseclub.

When you encounter a "Your split amounts don't add up to the total specified." message while splitting a transaction, it means you'll need to go into the expense account that created your error and turn on its option to make it billable, then apply an income account.

Here's how:
 

1. Use the Gear icon, then go to Chart of accounts.
2. Click your expense account that caused the error. Edit it.
3. Check its box to make it billable.
4. Apply an income account.
5. Save your changes.

I've also included a detailed resource about working with this message which may come in handy moving forward: Bill Split amounts do not add up

Please feel welcome to send a reply if there's any additional questions. Have an awesome Thursday!
