Bindings arent working

my mqtt.cfg is just using the url=tc because i dont care that much about having a password but is my item code correct?

all i want to do is to be able to publish to the subcribed topics thats all i dont mind too much about states.

But looks right
Switch mySwitch {mqtt=">[mybroker:myhouse/office/light:command:ON:1],>[mybroker:myhouse/office/light:command:OFF:0]"}
