# Message Sensor can't detect/receive message

This may sound stupid idk but my message sensor can't seem to read the message sent by one of my actuators? I have a plane which plays its animation when a key is pressed and has an actuator which sends a message to my human with the subject "Earthquake". My human has a message sensor with the same subject. It is supposed to match right? Or am I doing it wrong? Replies will be very much appreciated thank you!

• Yes the subject in the message actuator and sensor need to match, they are case sensitive and exact, an extra space will break it. Is the actuator sending to the right object? You can leave the object empty in the message actuator to have it sent to every object. Are you sure that it isn't receiving or is the actuator attached to the message sensor not working?

In the first screen shoot, I have a Keyboard sensor, on the object ground plane, send a message to all objects (the empty To field) with a Subject of somthing (with the misspelling).
In the second screen shoot, Now on the object human. There is a message sensor listening for a message with the subject somthing. When it receives a message (from any object) with the subject somthing the connected action actuator plays the animation.
