My peugeot 206 won't start?

A click and nothing else means one of two things:

1) a Flat battery 2) bad battery connection.

Chekc that the battery connectors are tight and try again. If you still havce a problem recharge you battery. To stop it happening again, check that the red charge light is going out when the engine is running. If that is OK and the battery continues to go flat its time for a new battery
