adding totals?

[moynzzee]

hi im new to programming, started only a few days ago, so i don't know most of the definitions or jargon!

but iv got a a asisignment where i have to a daily total and add it to the weekly total if that makes sense?

basically

weekTotal = 0 + dailyTotal

now i know thats not the proper way beacause it resets each time. what i wana do is

weekTotal = weekTotal + dailyTotal

but i dont know how to do it! i read something online about using += to do it but when i do i get end of statement expected.
what do i do?

[ident]

weekTotal = weekTotal + dailyTotal

would work same as below. You must be doing something else. Please post your code.

weekTotal += dailyTotal

I would imagine that this is a scope issue. If you are declaring 'weekTotal' inside a method then it only exists inside that method, so it's value defaults to zero each time. If you want it to maintain its value between method calls then it must exist outside the method, i.e. you must declare it outside the method.

erm do you mean a global variable? if so how do i go about setting it up? iv only started rogramming recently as part of my ict class, and had a few lessons so fr, so tryin to do a crash course!

Unless I have grossly misunderstood, you are pretty much there. Try this on for size.

(If you need to enter values through text boxes on a form. Try something like this.)

No I don't mean a global variable. I mean just what I said. A variable declared inside a method (Sub, Function or the Get or Set of a property) is a "local variable" while anything declared outside is a "member variable", also known as a "field". Any properties, methods, events, non-local variables, etc, that you declare within a type, e.g. a form, are all known as members. E.g.

Public Class SomeType
 
    Private memberVariable As Object
 
    Public Sub SomeMethod()
        Dim localVariable As Object
    End Sub
 
End Class
