SELECT And Stored Procedure Producing Different Results?!?!?

I ran my SP in QA and it brought back some data from my live database but I had my test DB selected from the DDL at the top of the screen.  So i ran a Select statement on the whole table in a different query window (with the same parameters)and it gave me the correct info.  Any idea y?  They both should be bringing back information from the same table not one from my live DB and one from my TEST DB.  Please help me--I'm so lost!min max rate <----This is what my stored procedure brought back(data from my live DB) ---it has parameters 90 100 .4080 89 .3070 79 .2559 69 .1549 58 .10The stored procedure is as follows:  CREATE PROCEDURE dbo.sp_WageMatrix_GetRate( @CompanyID nvarchar(2), @FacilityID nvarchar(2))AS SET NOCOUNT ON;SELECT [Min], [Max], Rate FROM Performance.dbo.WageMatrix WHERE (CompanyID = @CompanyID) AND (FacilityID = @FacilityID) AND PeriodID = dbo.fn_GetCurrentPeriod(CompanyID, FacilityID)ORDER BY RangeIDmy select statement brought back the following:min max rate 90 100 .4080 89 .3070 79 .2560 69 .15and I ran the following select statement:  SELECT [Min], [Max], [Rate] FROM [PerformanceDEV].[dbo].[WageMatrix] where companyid = '21' and facilityid = '01' and periodid = 2order by rangeid
