If problem

--------------------------------------------------------------------------------

Hi,

I have 3 variables which store values like this

lunch="1"
dinner="2"
snacks="3"

if lunch is selected then the value is 1 if not its blank
if dinner is selected then the value is 2 if not its blank
if snacks is selected then the value is 3 if not its blank

If all 3 are selected the price is $12
if 2 of them is selected the price is $8
if one of them is selected the price is $5

so here is the code

Code:

If lunch="1" And dinner="2" And snacks="3" Then
	finaltotal="12"
End If

If (lunch="1" And dinner="2") or (lunch="1" And snacks="3") Or (dinner="2" And snacks="3") Then
	finaltotal="8"

End If

If (lunch="1") Or (dinner="2") Or (snacks="3")  Then
	finaltotal="5"
End If

but its not working any idea

need to use ElseIfs ... the way you have it now, is that you're going to go through each if/then statement ... hence you could change your variable value. try something like this:

Code:

If lunch="1" And dinner="2" And snacks="3" Then
	finaltotal="12"
ElseIf (lunch="1" And dinner="2") or (lunch="1" And snacks="3") Or (dinner="2" And snacks="3") Then
	finaltotal="8"
ElseIf (lunch="1") Or (dinner="2") Or (snacks="3")  Then	
             finaltotal="5"
End If

Any particular reason your variables need to be 1, 2 and 3 (and strings no less). If you can make it so that variable=1 if select, 0 if not, then this becomes a much easier problem by using a SELECT CASE.

Code:

SELECT CASE lunch+dinner+snacks  ' assume Int, otherwise convert
CASE 3 
  finaltotal = 12
CASE 2
  finaltotal = 8
CASE 1
  finaltotal = 5
CASE ELSE
  finaltotal = 0
END SELECT

In the event the values just have to be different, can you make it 1, 2 and 4? Then

Code:

SELECT CASE lunch+dinner+snacks  ' assume Int, otherwise convert
CASE 7 
  finaltotal = 12
CASE 3,5,6
  finaltotal = 8
CASE 1,2,4
  finaltotal = 5
CASE ELSE
  finaltotal = 0
END SELECT
