Reverse For Loop

In my game I am going through a list box of numbers and removing those entries in another list box. So if listA has 1,5,6,8,20 it would remove the entries in the spots 1,5,6,8,20 in listB.

Since when you remove item 1, it changes the location of 5-20 I want to go in reverse, from 20,8,6,5,1. This way none of the items actually change location. I am using a forLoop of

VB Code:

maxArray = frmGameScreen.lstRemove.ListCount - 1
        ' This loops in revers so it does not affect where the items lie in the listbox
        ' Example : removing item 20 does not effect where item 4 is
        For forLoop = maxArray To 0
            frmGameScreen.lstComputer.RemoveItem (frmGameScreen.lstRemove.List(forLoop))
        Next forLoop

I have done reverse loops (large to small) before but for some reason the entire forLoop is skipped.

"Step -1" is missing from the end of the For command.

Now how did I miss that? I swear I had it. Thanks. I was looking at the code for so long I am starting to see things that arent there.
