Bukkit

Hello,
I have a little problem with the Traincarts,
The plugin is working very well, there is no problem,
but we don't know why the Ticket system is not working.
We placed a Ticket sign under the rails with:
[+train]
ticket
buy
1,5
When we place it, it says that the sign was successfully created, but
after, when the train is driving over that sign, he don't take our money.
We have tested it a bunch of times with:
[+train] or [!train]
ticket
buy or add
1,5 or 1
Our economy plugins installed:
Vault

Problem solved
