My question is I want to remove duplicate order numbers in other words ditch
*one* of the Mike Smith rows there's a duplicate order number there.
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]
