Calculation in Database and gridview in VB code

Can you share the Table Structure of the tables involved. A Database Diagram screenshot would be helpful

YES, I AM ATTACHING THE TABLE

I HAVE TWO FUNCTIONS FOR THIS 

ONE

USE [ANIL]
GO
/****** Object:  UserDefinedFunction [dbo].[getBTechBECount]    Script Date: 10/06/2012 19:48:33 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE FUNCTION [dbo].[getBTechBECount] 
(
        @ENTRY_COURSE as varchar(50)
)
RETURNS varchar(max)
AS
BEGIN
DECLARE @Count VARCHAR(MAX);

select @Count = COUNT(*) from COURSE_intake 
where HAQ in ('BTECH','BE')
and ENTRY_COURSE = @ENTRY_COURSE

RETURN @Count
END

TWO

USE [ANIL]
GO
/****** Object:  UserDefinedFunction [dbo].[getMedCount]    Script Date: 10/06/2012 19:49:48 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE FUNCTION [dbo].[getMedCount] 
(
        @ENTRY_COURSE as varchar(50)
)
RETURNS varchar(max)
AS
BEGIN
DECLARE @Count VARCHAR(MAX);

select @Count = case when MED_CAT = '11111' then 0 else 1 end
from course_intake where
--where HAQ in ('BTECH','BE')and 
entry_course = @entry_course

RETURN @Count
END

the code and the databse structure is as above

I cannot see any screenshot

please guide me how to attach the image
