I’m getting this error message >>> Typeerror: Cannot read Property 'pop' of null (line 5, "Code" file)

Question

I’m trying in Google Sheets to sum the values of cells that have the same color background. The problem is that the code is returning me the following message:

" Typeerror: Cannot read Property 'pop' of null (line 5, file "Code") "

I do not know how to solve, I am very beginner. If anyone can help me. Follow below the code.

function sumByColor(sumRange,colorRef) {
  var activeRg = SpreadsheetApp.getActiveRange();
  var activeSht = SpreadsheetApp.getActiveSheet();
  var activeformula = activeRg.getFormula();
  var countRangeAddress = activeformula.match(/\((.*)\;/).pop().trim();
  var backGrounds = activeSht.getRange(countRangeAddress).getBackgrounds();
  var sumValues = activeSht.getRange(countRangeAddress).getValues(); 
  var colorRefAddress = activeformula.match(/\;(.*)\)/).pop().trim();
  var BackGround = activeSht.getRange(colorRefAddress).getBackground();
  var totalValue = 0;
  for (var i = 0; i < backGrounds.length; i++)
    for (var k = 0; k < backGrounds[i].length; k++)
      if ( backGrounds[i][k] == BackGround )
        if ((typeof sumValues[i][k]) == 'number')
          totalValue = totalValue + (sumValues[i][k]);
  return totalValue;
};

On lines 5 and 8 change ; for ,. In Brazil this is the standard tab.

function sumByColor(sumRange,colorRef) {
  var activeRg = SpreadsheetApp.getActiveRange();
  var activeSht = SpreadsheetApp.getActiveSheet();
  var activeformula = activeRg.getFormula();
  var countRangeAddress = activeformula.match(/\((.*)\,/).pop().trim();
  var backGrounds = activeSht.getRange(countRangeAddress).getBackgrounds();
  var sumValues = activeSht.getRange(countRangeAddress).getValues(); 
  var colorRefAddress = activeformula.match(/\,(.*)\)/).pop().trim();
  var BackGround = activeSht.getRange(colorRefAddress).getBackground();
  var totalValue = 0;
  for (var i = 0; i < backGrounds.length; i++)
    for (var k = 0; k < backGrounds[i].length; k++)
      if ( backGrounds[i][k] == BackGround )
        if ((typeof sumValues[i][k]) == 'number')
          totalValue = totalValue + (sumValues[i][k]);
  return totalValue;
};
