1) Please read through the
SPON Money discussion thread and see is your specific problem has been solved already.
2) Have a look at the demo mission since that is known to work, since I admit the instructions for this old script are patchy at best (and misleading at worst).
3) Start by copying the stuff from the demo mission, then adapt it, step by step, to what you want. If you try to configure everything at once, it will most likely break and you won't know what is wrong.
4) If that doesn't sort you out, please give me some more specific questions than "How do you work it?", preferably in the
SPON Money discussion thread, so that other people can easily find your question and any answers I give.
However, don't worry about strugging with this script. It is a very complex script, and, in order for it to be useful in a large number of circumstances, it is highly configurable. On the other hand, this means that it can be very difficult to configure...
