Syntax Trouble With Int In Stored Procedure

Dear Forum,

I am adding a new column name to my Stored Procedure called HeadlinerID.  It is an Int that is 4 characters long.  I seem to be putting this in incorrectly in my stored procedure.  I have tried it like: @HeadlinerID int(4), and @HeadlinerID int,  and both ways I get the error below:

Error 170: Line 16: Incorrect Syntax near ‘)’. Line 40: Incorrect syntax near ‘@Opener’.


Is there a trick to putting in integers in a stored procedure?
 
Thanks,
