Trying to get slider to work on a tmc2209

I am trying to get a slider to work with a a4988 stepper driver. But I keep getting stuck.
If I change the stop_action to

   stop_action:
      - stepper.set_speed
          id: my_stepper
          speed: 250

then it changes the speed if I push stop so that works.
But when i change it with a lamba function it gives me this error

 "/config/esphome/esp-motor.yaml: In lambda function:
/config/esphome/esp-motor.yaml:63:14: error: 'level' was not declared in this scope
           speed: !lambda 'return level/100.0;'
              ^~~~~
/config/esphome/esp-motor.yaml:63:14: note: suggested alternative: 'Server'
           speed: !lambda 'return level/100.0;'"

Can somebody help me and tell me what I doing wrong?
And how i can change it.

GOT IT WORKING IN A DIFFERENT WAY.
