Need help with server script installation

Hey folks,

I'm pretty new with installing scripts, however i've successfully get few to work.
First i had problems where i find fn_self actions.sqf file, till i realized i had to copy it from local dayz code.
That way i have now working basic scripts like selfbb, sarge ai framework, action menu, snapping, intro song... etc.

But with few scripts like side missions i've faced a problem.

Trying to install that...
