won't add sum of an array

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

var x : int
%integer variable for number of guests
var pizzatype : string
var totslices : int

loop
    cls
    put "Please enter number of guests: "
    get x
    put "Please enter your type of pizza (pepperoni, vegetarian or hawaiian"
    get pizzatype
    var slices : array 1 .. x of int
    %creates an array for asking for the number of slices for all the guests

    if pizzatype = "pepperoni" then
        for i : 1 .. upper (slices)
            put "Please enter how many slices you would like of pepperoni pizza, person", i
            get slices (i)
            totslices += slices (i)
        end for
        put totslices
    end if

    if pizzatype = "vegetarian" then
        for i : 1 .. upper (slices)
            put "Please enter how many slices you would like of vegetarian pizza, person", i
            get slices (i)
            totslices += slices (i)
        end for
        put totslices
    end if

    if pizzatype = "hawaiian" then
        for i : 1 .. upper (slices)
            put "Please enter how many slices you would like of hawaiian pizza, person", i
            get slices (i)
            totslices += slices (i)
        end for
        put totslices
    end if
end loop

I can't seem to get totslices to set equal to the sum of the slices array and then output the sum. Any ideas?

You need to initialize "totslices"
And just curious, why is the number of guests variable "x" ? The other ones make sense, but not that one :P

Initialize "totslices" like gitoxa said.

To do that, just add := 0 after the declaration (var totslices....).

Yeah I figured that out, I felt so dumb once I figured it out. I'm so used to the default value of an integer being 0. Oh well, this is how one learns I guess.

x was just a placeholder, I like to have working code before I change things I'm meaning to change. I really don't know why.
