Calculator help, displaying scores?
I want to be able to display up to 10 numbers. For example, if the user enters more than 10 scores, a dialog box should appear stating that they are only allowed to enter 10 scores. When the user clicks the Add button, the Score textbox should clear so the user can enter another score. How do I do this? Any help would be greatly appreciated.

Thanks, do you know how to sort scores in ascending order and display them in a message box?
My display button displays shows a message box, but it doesn't show my scores, it shows the list of the amount of numbers. For example, if I typed in 4 numbers, it displays 0, 1, 2, 3.
What am I doing wrong?

Thanks, it doesn't display 0, 1, ... anymore.
Though, when I typed in 1, 3, 7, 9, 14, 27, 39, 54, 43, 55. I then got 0, 1, 4, 11, 20, 34, 61, 100, 154, 197.

I can't see where in the code you have posted so far, but it looks like you are somehow managing to go all Fibonacci sequence on your list of numbers.

Thanks, it works. I want to create a new list after pressing the clear button. How do I do it?
I tried to and I end up having the textboxes initially cleared and then I add more numbers after and average and total don't reset.
