Simple math problem?

Hello friends

I need to implement the following

In a "Tex Box" income numbers, pressing the button, each of these numbers (separately) is loaded into an ARRAY.

What I do is the following

If I enter the following number "123456"

Is loaded into the array:

Set value at 0 to mid (TextBox.Text, 0.1)

Set value at 1 to mid (TextBox.Text, 1.1)

Set value at 2 to mid (TextBox.Text, 2.1)

Set value at March to mid (TextBox.Text, 3.1)

Keep the number of characters in a variable "Char"

system -> Set char to len (TextBox.Text)

And then be added together and divided by the total number of characters, where I apply the following

Text2 -> Set Text -> "Sum:" & (Array.At (0) + Array.At (1) Array.At (2) + Array.At (3) + Array.At (4)) / char

But I manage to find the result as it always shows me = 1

This is te .CAPX

In that I'm wrong?

Thank You
