[FX.php List] Creating summaries on the fly,

[Bob Patin]

Dale,

Makes sense, but that's not the problem. I've already gotten my page  
to show summaries and subsummaries. What I need is to show the  
percentage of the subsummary total for each LINE of the subsummary.  
Here's what I'd like to have:


Total vehicles	25 (from foundCount)

Ford Taurus	3	30% <-- this is what I need to insert after the foreach  
loop
Ford Focus	7	70% <-- ditto here

Total Fords	10	40%	(I can get this because I already know the  
foundcount)

Honda Accord	5	33%
Honda CRX	10	67%

Total Hondas	15	60%	(also obtainable because I know the foundcount)

Unless I'm missing something in your example...

Bob
