Rig legs

Hi guys,

i watched the tutorials of Cartesian Caramel here:

I got the points working - no problem. But the IK legs parts don’t work for me.

Did anybody got that part working?

and can maybe help me what i did wrong?

my node tree:

and sorry for that question, but you can only answer that if you watched that tutorial. It is pretty long…but hopefully someone watched it from you.
