I'm attempting to filter a dropdown list based on the value of a parent dropdown list. Everything appears to be configured correctly, but the second dropdown is returning all of the values vs. the expected filtered values.

Parent Stored Procedure

USE  TempLaborMasterDB]
GO
/****** Object:  StoredProcedure  dbo]..SP_Get_All_Location_Types]    Script 
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE  dbo]..SP_Get_Location_Types]
-- Add the parameters for the stored procedure here

AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
SELECT LocationTypeID, LocationType 
FROM dbo.LocationTypes

END

Child Stored Procedure

USE  TempLaborMasterDB]
GO

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE  dbo]..SP_Get_Locations_Name]
-- Add the parameters for the stored procedure here

AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
SELECT 
      LocationName,LocationTypeID
FROM dbo.Locations

END
