Hi,
I would like to know for the Milking Automation Challenge, do we need to push the cow inside before the pushing the red leaver?
If we don't push the cow inside will it block the milk? Will it cost points. 
In the challenge the point says only for getting the milk out. it did not say anything for pushing the cow BUT the video shows pusing the milk.

Thank you for your help
