1 MeV protons through a thin film of water

Dear Experts,

I am trying to look at the scattering angle of protons after
travelling through a water film of water of thickness 0.01 cm (The inp
file is attached). The problem is that I am not seeing any protons
behind the water film. I played with the following cards, but couldn't
get to work.

Please advice me...

Thank you !
