Kanga, yes there is a way of providing a fairly simple way of collecting the order information. The psof forum allows you to set up and have a poll. This allows people to "vote" for different options and you can allow each person as many "votes" as you like. That person oncethey have voted can also change thier votes.
So if each option was a piece of kit, someone could "vote" for the bits of kit they want. If they change thier mind they can change this when ever they want. This would immediatly give the numbers of each bit of kit.
However, for someone to easily find out who wanted which bit of kit, rather than simply quantly of each will require some changes to the code. This can be done (there are variouse changes already published) but it will probably be a few days before I could do this.
If there are not too many types/sizes of kit each option could include the size. i.e.
Tri Shorts (S)
Tri Shorts (M)
Tri Shorts (L)
Tri Shorts(XL)
e.t.c. but this might make the poll rather long... The alternative would be to work out the sizes later.
Don't know if this would help?
