Aaaand, I still don't get the purpose of _this select 0. What it does or why it needs to be there. I'd look at the comref regarding that, however flashpoint1985's page is usually so unreliabe I can't access it half the time.
I understand a little more as to why you use this ["MarkerName","UnitType",GroupName,UnitsSide] exec "nameofscript.sqs" to exec the script
However, my way is simpler in terms of undertsanding, It may not be functional. However for the most part I understand what each and every part does (or is intended to do). I think I'm already way in past over my head. Creating multiple scripts suits me fine so long as they're at the elementary level of scripting, which is all I can understand right now. All I wanted was a way to test if there was a particular unit was in a certain quantity. Now I'm left with more questions than answers...
