Question : Select statement is trimming off the leading zero

I have a stored procedure that selects a couple values and then does some calculations and then returns.  When the first select (select @zone = @ServiceLevel from....) the @zone gets a value of 45.  When I do this select without putting it into a parameter, I get 045.  The value that @Zone is storing needs to be 045 not 45.

Any Ideas?  @Zone is a nvarchar(15) so I thought that this would keep the leading zero.
