Well then I just found the solution to my problem. Turns out it was because there was a holiday but for some reason the sims team decided to put the 'go to school' button there even though its a holiday and you can't go to school. Maybe they should fix that so someone else wont have to spend ages trying to figure out why they cant send their kids to school. Cause just before theyre about to go to school it says 'Holiday' instead of 'School starts in -' but then when school should start the 'go to school' button appears but clicking it doesnt do anything.
