Undeclared variable from modules

[alasdairs]

Hiya,

I'm currently working on a project and just decided to rewrite one of the forms to base it on one of the cloud solution sample forms, and added a few modules into my solution, but when I did I got a bunch of warnings saying 'reference to undeclared variable or property [variable]'.
There are a bunch of variables that are undeclared like '_super' or 'dateForm' etc. Quick fix doesn't seem to work and I'm wondering whether theres an easy way to fix this issue. It's giving nearly 700 warnings in the project.
I'm just not sure what to do.

Thanks!
Alasdair
