When applying for a Trust Account Number in the T3 Module the T3App form picks up the Trustee names from the Info section of the T3 return. If the first and last names of the trustees are entered correctly in the Info Screen, they transfer over to the T3App form with a comma between the first and last name.
Instead of the trustee names displaying on the T3APP form as
Lastname , Firstname
the trustee name displays as
Firstname , Lastname
