Users not created during install

[theswimmingfrog]

I am making an automated install for school. I have about 7 accounts I have to be made when the install runs. None of them are created and I've recreated the ISO many times. I run this install on a VirtualBox VM and completely formatted the disk multiple times but it never fails to not create the users. What could be the problem here?
