TypeError: props.toggleConfirmation is not a function

Looking for a solution as the code I've written is identical I believe but when I click "is confirmed" I receive this error

TypeError: props.toggleConfirmation is not a function handleConfirmation src/MainContent/GuestList/index.js:18 15 | name={guest.name} 16 | isConfirmed ={guest.isConfirmed} 17 | isEditing={guest.isEditing}

18 | handleConfirmation={() => props.toggleConfirmation(guest.id)} 19 | handleToggleEditing={() => props.toggleEditing(guest.id)} 20 | setName={text => props.setName(text, guest.id)} 21 | handleRemove={() => props.removeGuest(guest.id)}

let me know how i can better diagnose this issue.

Thank you
