I cant control multiple bone joints

hello all
I have been able to take full control of a bone joint when there was only one bone in the model,but when i had a model that had more that one bone,I could for some reason not control any of them,I checked the names of the bones.
I have no idea what is going wrong.
Can anyone help me please
Thanks greatly.
