Computer logoff after waitng 30 minuter from Idle stage

Hello,

I am trying to crate a GPO with below rules. First one is achieved but facing problem with second,

1. If user is not using the workstation for 15 minutes, the workstation should get locked automatically..... (Achieved)
2. If the logged user does not use the same workstation again for next 60 minutes, then workstation get logged off.

I tried below to achieve 2nd rule but did not success. My computer is getting logoff as soon as computer get locked.

Thanks in advance :-)

Regards
