# IK rig breaks when I add a pole target

I've been trying to do rigging recently, and when I add a pole target to my IK rig, my character's foot just slides up and down the leg, which remains stiff. I've had this problem for a while and I have no idea how to fix it. I have a link to a video to show exactly what's going on: https://drive.google.com/file/d/1qHK51yggU4sGDHTB-A6aoSrFe8iFpfQZ/view?usp=sharing
