Syntax Error Near '@Count'

I need your help:





I want to get the total number of expired messages of two tables.





But if gives me this error:





Line 17: Syntax error near '@Count'





What did I do wrong? Am I not allowed to add two Integers??








CREATE PROCEDURE Portal_GetExpired





(


@Count int OUTPUT


)





AS





SELECT Count(*) as x


FROM Portal_Announcements


WHERE ExpireDate < GetDate()





SELECT Count(*) as y


FROM Portal_Events


WHERE ExpireDate < GetDate()





@Count=x+y





GO
