Ok... so my program is like a store(you can buy things, and choose the quantity that you want for the item), and i have an array for the quantity of each item and i set the quantity to 0 at the begining, so what i want to do is display a message only if there is at least 1 item with a quantity higher than 0. So how do i make it go through all the quantities in the array, and chek if there is a value higher than 0, and once it finds at least 1 value higher than 0, then it will display the message Question

You got it, but did you get it the easy way? I'm guessing you did some stuff with boolean variables to make it work. The easier way is to use a function. If the condition you are looking for is true, result true. Go through the for loop like that, and when you finish the for loop, result false. As soon as a function reaches a result line, it results the value and terminates. So, as soon as your condition is true for any element of your array, the function will result true and exit.

code:

function checkQuantity : boolean  %the : boolean means the function returns a boolean value
  for i : 1 .. uper (yourArray)
    if yourArray (i) > 0 then
      result true
    end if
  end for
  result false
end checkQuantity

If you don't know functions, check the tutorial on this site. Search for it, I believe tony wrote it. Smile
