Just to add to Azmo 's answer...

I in fact removed all trailing semi-colons from the code:

// check if an item can be checked off
function checkedOff( need, have ) {
  var retStr = "nope"
  if( have >= need ){
    retStr = "yep"
  }
  return retStr
}

And discovered, that when doing this over a large range you can also max out the acceptable number of calls to the API.

To get around it I added an IF THEN check around my custom script call.

So instead of:

=checkedOff(H10,H11)

Use something like this to check for a populated field before execution:

=if(H17<>"-",checkedOff(H10,H11),0)
