leg move in pose mode moves other leg in my blender i created a character and his armature with bones assigning with automathic weights to the body, dont ask me hard questions cause im newbie, i got some problems with my character first i tryed to assign evertying to 1 object so i can move the entire object in animation, not working cause i did part of my character without scalling, so when i move all the body the other part stays there, second when i try to move a leg the other leg moves to and it becomes kinda buggy, i already tryed to create the bones again and again but nothing works, and i need to end this really fast if i can get some help i put the file in upload and send the link here

  Here is the blend file that i uploaded in the website
you need to weightpaint your model. in pose mode you need to hold shift and right click your model. after that go to weight paint mode. then click a specific bone and paint on the mesh its influence. red means this face is affected 100% by the bone. blue means zero. if this is too complex, you should watch one of the many tutorials on youtube :)
