Why isn't this CTE recognized? - sql

Question

I'm trying to pull in student majors to this sql by using a CTE, but when I try to add the CTE fields, or join the CTE with an implicit join, which works fine in other queries, oracle throws the error 'invalid identifier'. Any thoughts?
This is only the first part of many unions in this sql but I've seen examples where a CTE works fine with unions so I don't think thats it, and besides that when I run this code without the unions I get the same errors, 'invalid identifier'.

Answer 1

Adding the CTE to the from clause made it work. Forgot about that little detail.
