Sigma Notation In Adobe Acrobat Javascript!

[Flynn0101]

Hello!

I've been trying to add a function for adding sigma notation into acrobat so I can have a responsive code for summing totals the following script doesn't work!

function mathSigmaSymbol (startIndex, endIndexInclusive, iteratorFunction) {
  let accumulator = 0;
  for(let i = startIndex; i <= endIndexInclusive; ++i) {
    accumulator += iteratorFunction(i);
  }
  return accumulator;
}

Please help me!

Change "let" to "var".
