Hi there @mrslerksx. You don't go with your Sim to their audition, they disappear and then you get a message if they passed.
You then get the option to go to the acting gig with them a few days later. Just like the Get to Work careers it will give you the option to go with them or Send Alone.
If they're successful in their audition the career panel will tell you what day the gig is. Are you seeing a work day in the career panel and waiting until that day to see what happens? If not I'd do that and if you don't get an option to travel with them to the actual gig and if you have Get to Work I'd check if you get the option to travel as a Doctor/Police/Scientist to see if they are working. If any of them are not working then that would be a bug, so let us know and we can help you to report it.
