我有一个 onEdit 功能，我需要从一排复选框中搜索未选中的复选框 [Google Sheets]

Question

关于我的电子表格：

• 第 1 行最后一列的单元格 B1 充满了复选框。
• 第 5 行到第 16 行的 A 列充满了复选框。

我需要从这个宏中得到什么：

• 我想创建一个 onEdit 函数，当单元格 A5:A16 中的复选框被选中时运行。
• 我希望它首先检查第 1 行中的复选框并找到第一个未选中的复选框。
• 然后我希望它识别该列，以便该行（即刚刚选中的复选框的行）和列（即第 1 行中第一个未选中框的列）中的值。
• 我想取这个单元格中的值，然后从同一列第 17 行的值中减去。

这是我的电子表格示例的链接：https://docs.google.com/spreadsheets/d/1xet-VnYidcVitRx4ffjimXBjGNDQoYl2SbaxfIUJV7A/edit?usp=sharing

到目前为止我的尝试：

function onEdit(e) {

  //This IF statement ensures that this onEdit macro only runs when cells A5:A16 is edited
  if (
    e.source.getSheetName() == "Finances 2020" &&
    e.range.getColumn() == 1 &&
    5<=e.range.getRow()<=16
  ) {

    //Cells A5:A16 are checkboxes. This section ensures the following script only runs when the checkbox is checked (and not when unchecked).
    var checkboxtest = e.range.getValue()
    if (checkboxtest == true) {

      //THE ABOVE HAS BEEN TESTED AND WORKS SUCCESFULLY.
      //I CANNOT GET THE FOLLOWING TO WORK:


      var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
      var Finances_2020 = spreadsheet.getSheetByName("Finances 2020");
      var Billrow = e.range.rowStart
      //Deduct the value in the first unchecked column of the edited row, from the value in row 17 of that same column:
        var AllFortnightCheckboxes = Finances_2020.getRange(1, 30, 1).getValues();   //Create a variable consisting of all the values in the row 1 checkboxes. This is used to find the first unchecked box.
        for(var i=0; i<AllFortnightCheckboxes.length ; i++){  //This For loop will run through all of the row 1 checkboxes.
          if (AllFortnightCheckboxes[i] == false){        //This if statement will look for the first unchecked box.
            //Copies the value to row 17 of that column:
                   //*******I have not been able to test the above before writing this bit of script. Once I have identified the column of the first unchecked box in row 1, I should be able to create this section.
            //Stop once the first unchecked checkbox has been found:
            break;
        }
      }
    }
  }
}
;

function onEdit(e) {
  //Logger.log(JSON.stringify(e));
  //e.source.toast('Flag1');
  var sh=e.range.getSheet();
  if(sh.getName()=="Finances 2020" && e.range.columnStart==1 && e.range.rowStart>4 && e.range.rowStart<17 && e.value=="TRUE") {
    //e.source.toast('flag2');
    var rA=sh.getRange(1,3,1,sh.getLastColumn()-2).getValues()[0];//flattened
    //Logger.log(rA);
    for(var i=0;i<rA.length;i++) {
      //e.source.toast('flag3');
      if(rA[i]==false) {
        //e.source.toast('flag4');
        var col=3+i;
        sh.getRange(17,col).setValue(sh.getRange(17,col).getValue()-sh.getRange(e.range.rowStart,col).getValue());
        break;//stop after first one
      }
    }
  }
}
