So the end result I want is -

Cooperation, Curriculum Linked Activities, Familiarization, Fun, Personal Challenge, Personal Development, Personal State Management, PSE, Self Belief, Skill Acquisition, Support, Training Course

BUT...

It needs to be depandant on the #N/A's as it could change too -

Cooperation, Curriculum Linked Activities, Familiarization, Fun, Personal Challenge

I can get it so the end result is - Cooperation, Curriculum Linked Activities, Familiarization, Fun, Personal Challenge, Personal Development, Personal State Management, PSE, Self Belief, Skill Acquisition, Support, Training Course, , , , , , ,

But need to exclude these last commas.

Hope that makes sense
