help! about adding schools

I’ve successfully added separate industries - a business track one - with the icons and prereqs etc

However when I tried to do the same thing for the evening classes, add a separate school for business, that didn’t work.
is there something special i’ve got to do? because it doesn’t seem right to not give these classes their own school.

apart from that, great game! I’ve spent hours modding stuff… because i am at heart a control freak who must have her way :unamused:

Show us what you’ve got up to and maybe we can advise :unamused:
