Eu não consigo descobrir por que (ou talvez você simplesmente não possa fazer isso) Eu recebo o erro de fora do escopo

Deve declarar a variável escalar "@CompanyGroupSites_Master.

Então é assim que eu não consigo acessar minha variável Table dessa maneira dentro do meu Cursor, ou eu devo ter perdido algo simples que mantém essa variável de tabela fora do escopo quando referenciando de dentro do corpo do cursor?
