If else problem

Today is my first time to test simple if else in automation, but i can’t save it. It shows this error message:

Message malformed: offset on should be format 'HH:MM', 'HH:MM:SS' or 'HH:MM:SS.F' for dictionary value @ data['action'][0]['choose'][0]['conditions'][0]['for']

If motion sensor binary_sensor.a4b0003832 is on, turn on switch.belkin_smart_plug_1, else turn on switch.belkin_smart_plug_2.

alias: if else
description: ''

  - platform: state
    entity_id: binary_sensor.a4b0003832

            state: ''
            for: 'on'

        sequence:

            target:
              entity_id: switch.belkin_smart_plug_1
    default:
      - service: switch.turn_on
        target:
          entity_id: switch.belkin_smart_plug_2

for: needs a time (HH:MM or HH:MM:SS) and state: needs a state.

Thanks Tom.
Now, i try another new code, why switch.belkin_smart_plug_1 cannot be turned on once the binary_sensor.wemo_motion is on?
Every time i trigger the motion, only switch.belkin_smart_plug_2 will turn on, nothing happen to switch.belkin_smart_plug_1. Why?

If the motion is triggered, turn on smart plug 1, after that turn off smart plug 2. Else, turn on smart plug 2, after that turn off smart plug 1.

        target:

Remove this from the choose condition:

Thanks. Brilliant
