Ok Ive been tinkering with your solution and my ignorance of arrays has
stumped me again. It looks like I should be recreating the array along the
lines of (pseudo code)
array (oldelement1,oldelement2)= newarray (newelement1,newelement2)
If element1 is the key this will remain the same and element2 is the
cumulative total will change. So I tried
$data['key']['accum'] = $key =>$accum += $item['profnloss'];
initially, but it didnt work
I ended up with
foreach($data as $key=>$item)
{
if ($item['profnloss'] > 0)
$data['key']['accum'] = $accum += $item['profnloss'];
else
$data['key']['accum'] = $accum;
}
This sort of worked a bit in that in the displayed results the first line
had no values exept the overall cumulative total. ie
Held Order- Sell Date- Profit/Loss- Cumulative Total-1005.06506667
and all the other rows had all the other data exept the cumulated total. ie
Held Order-371 Sell Date-2007-05-03 16:14:00 Profit/Loss--39.98 Cumulative
Total-
Held Order-688 Sell Date-2007-06-01 12:42:00 Profit/Loss-158.5254068123
Cumulative Total-
Held Order-377 Sell Date-2007-06-11 16:21:00 Profit/Loss-80.9849999999997
Cumulative Total-
Held Order-750 Sell Date-2007-08-02 12:07:00 Profit/Loss-548.267993187701
Cumulative Total-
Again excuse my ignorance. What have I got wrong
