And I need to do it in either a for/foreach loop. Somehow there's got to be a simple way to check and only output non duplicate order numbers while I'm looping thru the data. Any help would be greatly appreciated. It looks like the array is sorted.

In pseudo code for i = 2 to n if x[1].order = x[i-1].order then

       unlink x[i-1]
