1.
outputLabel.Text = someListBox.Items(someListBox.SelectedIndex))

This may throw exception if listbox donot hav string object. So try to assign displaytext or someListBox.Items(someListBox.SelectedIndex).toString()

>>2. 36 right?

it can't be, the value of I range from 0 to 5 so its value after the loop is 6 (1 more then the greater value).
