Filming another script - production

Today, me and Amanda were given somebody elses script to act and edit, we chose Amanda to be acting and i me as director.
It was a bit confusing filming another groups script because the storyboard and the script didnt match towards the end, ie, the storyboard missed out a shot that was in the script.
Me and Amanda produced a script and storyboard for Stuart and Richard to film.
We also had to edit another groups footage, this got quite confusing.
