Stored procedure if exists not giving correct answer

I created a sql 2005 stored proc to tell me if the CRID I am searching for is approved by the supervisor. [SuperApproved] is a bit, [CRID] is char(36). Even if the CRID doesn't exist, I am still getting 1. Any help in writing this?

 SET NOCOUNT ON;

if exists(
 select [CRID]
 from [dbo].[CostReportTracking]
 where [SuperApproved] = 1)

 -- exists- cost report is Approved by Supervisor
 select 1
else
 -- does not exist
 select 0    
END

I think you need to add an and [CRID] = @myECR somewhere. Right now you are just checking if there is any record that has been SuperApproved.
