Cannot Add foreign key constraint Error 1215

Question

I am using Workbench 6.0 and having a frustrating issue I am new to SQl and would like to keep this as simple as possible at this point, I believe my tables are ordered properly to add contraints except for my TICKET table, no idea how to find what foreign key is having problems.

TICKET表中的DriverLicenseNo上的拼写错误和DRIVER表中的DriversLicenseNo
