Array Bounds

[salvelinus]

This should be simple, but it's not working.
The code below should show (to my mind) the values in the first dimension of the array, i.e., 12, 12, 13,...20.
Instead it shows 12, 12, then stops. This must be something obvious, but I can't see what the problem is. Any ideas? Thanks.

Dim i, j, l As Integer
Static x As Integer
Dim arrQuNumbers(,) = {{"12", "12", "13", "14", "15", "15", "15", "16", "17", "18", "20"}, _
                     {"16.1", "16.2", "17", "18", "19.1", "19.2", "19.3", "20", "21", "22", "24"}}
 
      
For i = arrQuNumbers.GetLowerBound(0) To arrQuNumbers.GetUpperBound(0)
      l = arrQuNumbers(0, i)
      MessageBox.Show(l)
