Use External Services in a flow unit challenge question

while trying to complete the badge for the external services flow unit, I continually get an error message. although my flow works as it should, and all of the details are exactly as asked for I continue to get this message 

"We can't find the correct settings in the 'Found Bank Account' screen. Make sure it was created according to the requirements, including the label, API name, showing the following account fields on a display text: Name: checkedAccount.name, Id: checkedAccount.Id Type: checkedAccount.z0type, and Available Bal: checkedAccount.availableBal."

I've gone back and double checked and everything is exactly as it should be yet I still am unable to complete the challenge
