problems with many to many relationship

problems with many to many relationship

pi make many to many relationship b/w proposals and sections but when we
run proposals new form it gives the error like this:/p p[Semantical Error]
The annotation @ManyToMany in property
Proposals\ProposalsBundle\Entity\Proposals::$sections was never imported.
Did you maybe forget to add a use statement for this annotation? how to
remove this error? here is my code of proposals and sections entity:/p
