Real 7

Im having Real 7 problems, and I know I am probably just missing one little thing. If anyone could give me a hand? (no spoilers. I HATE spoilers :P) anyways. I have logged into the teachers section, but when I change the grades (through both s****e ce and j******t) I a. Get no message and b. It doesn't stay that way. For scode I use mozillas and desktop. For the salary, it says I changed it but it doesn;t stay changed (that I don't actually expect to) and other than that I think I'm fine. But if you could please help? Thanks.

When you change the grade if you have a big red message said "YOU CHANGED GRADE", you don't need to look if it really change continue the challenge.

But thats my problem, I dont get the message
