Question : SQL Sever Store Proc Syntax for using LIKE in Where Clause with @Parameter

I'm losing my marbles (well at least my syntax).  What is the syntax for using LIKE with a A StoredProc in a WHERE Clause, e.g.

WHERE (CustomerName LIKE @CustomerName%)

It doesn't like the above.

Thanks for your help
