The title says it all....please bear with me as this could be complicated.

As part of a manifest system I have developed, I need to know how many passengers departing each location upon a route. For example

Route: A - B - C - D - E

Passengers can board at any location, and hop off at any location.

My goal is to choose a location, and know how many pax on board departing based upon when they boarded and when they are getting off.. For example, departing C could include pax who are:

A-D , B-E, C-D etc

As you can see on a longer route there could be quite a few possibilites.

I also need to ability to rearrange the route.

So.....and ideas anyone?

Task is very typical for scheduling.

Look in www.hierarchy.lv - under products must be TimeTable.

Instead of time use route points.

One "column" must be IN, next OUT and so on.

Add calculation fields in each record to summarize IN-OUT and get passenger count in each sub-route (C-E for example)

You can make as many points and destinations you want.

Thanks for the reply. I had a look but that doesnt seem to help me. Sometimes I have an idea on how to do this, but I write it down and it does my head in any time.

I'd appreciate any more specific advice.

Cheers
