In your page you are using ACT_create_object as a datasource microflow. At the moment you have this expecting a parameter called Numbers, but you aren’t passing this. 

To fix this, change your microflow to remove the Numbers parameter and the Show Page action, also change the return value to $NewNumbers.

Hope this helps.
