Rigging and Posing problems

Hey I’m pretty new to the modeling thing, and having trouble with moving the bones in pose mode on my model. I’m able to move 2 of them around, can’t rotate just grab move, the rest of the bones won’t do anything in pose. Not sure if there’s an option i turned on by accident or something, but it’s pretty frustrating, the location xyz are all greyed out, but they are unlocked, the 2 bones i can move don’t have them greyed out. Also the 2 moveable bones are the first 2 that i made in it. Thanks for any help i get

There is a detailed video tutorial that explains everything about rigging. It’s a must seeing for a beginner to blender rigging , like you and me
