Leg Drivers

I’m trying to model a flexion task in StandingModel and I need the legs fixed in the vertical direction (Instead of CoM driver). I’ve deleted the CoM driver from “JointsAndDrivers.any” folder and need to alter a driver for the hip joint.
I’m wondered how to do this.

Please help me to handle this problem. I’m using AMS v4.00 with AMMR v1.00 .
The zip file is attached. Please find JointsAndDrivers.any file.
Best Regards.

Dear Mohammed,

unfortunately, we do not give support or debug models from AMS and AMMR versions that go back so far.

Do you have an option to update your software and repository to a newer version?
Additional, what license are you using? I’m not even aware that Sharif University has a valid license.
