SQL Help

Hi. I am having problems with my coding for the following project.

On problems 2 and 3 Im getting a Missing Expression error and on 4 im getting a Not a group by expression error. Can someone take a look at my code and show me how to fix this?

oh and as a word of note. For problem 2 and 3 it says the error is on line 3 and for question 4 it says its on line 2.

Thanks

RE: SQL Help

Hi!
It's really hard to find errors without looking at the corresponding data. Could you provide some sample data sets from the actual tables here? That would help.
