problem adding amatures

im having probelms adding amatures as when i add amatures and go to pose mode
and pess g or r it deforms the model but i want it to move the arm like how to arm is on the model heres some pixz czn you tell me whats wrong


Have you created vertex groups for each bone?

dude this is obviouse u havent weight painted enough, remember to get even the vertices on the inside. and remmeber to weight paint every bone before u start the animation, and each spor tthat u want to move must be red and not green or yellow

i know that but i cant select all bones check the pics.

as i click the model and 1 bone ctrl p and parent to amature name groups

and it works but if i select the model and all bones i cant get them to work
