messages.......ugh

can someone tell me step by step how to use messages because no matter what i try it doesn’t seem to work

I’m just reading and condensing this out of the gamekit book but maybe it will help. I haven’t used them yet:

Add an actuator to the object and change it to a message actuator
leave to and body fields blank(equivalent to shouting it in the room)
fill in subject field with your subject: 10points

recieving object

sensor: message subject: 10points
wired to: and
wired to: property
prop:text
value:10

basicly, it’s saying that if it has the same subject, the message sensor will respond to the message actuator.

Like I say, it’s from the reading the game kit book. No one answered so I thought it might help.
