I don't understand why my google scripts script isn't working

Question

I've recently started using google scripts for google sheets and I can't get my onEdit function to work this is my code:

function onEdit(event) {
  var range = event.range;
  var spreadsheet = event.source;
  var r = event.source.getActiveRange();
  var activesheet = spreadsheet.getActiveSheet();
  var column = range.getColumn();
  var row = range.getRow();
  var spreadsheetname = activesheet.getName();
  var D5LOC = activesheet.getRange("D5").getValue();
  activesheet.getRange("D3").setValue(D5LOC);
  
  if(D5LOC == "FALSE"){
    activesheet.getRange("D6").setValue(activesheet.getRange("D5").getValue());
    if (!(column == 1)&&!(column == 2)&&event.value == "FALSE")
    {
        activesheet.getRange("D6").setValue(activesheet.getRange("D5").getValue());
        r.setValue("TRUE");

    }
  }
}

It's supposed to check every box that I've unchecked whenever a confirmation box is unchecked, however when I uncheck something it just doesn't do anything. please help

As far as I can tell this seems to be what your code currently boils down to:

function onEdit(e) {
  const sh = e.range.getSheet();
  const D5LOC = sh.getRange("D5").getValue();
  if (sh.getName() == 'Sheet1' && e.range.columnStart > 2 && D5LOC == "FALSE" && e.value == "FALSE") {
    sh.getRange("D3").setValue(D5LOC);
    sh.getRange("D6").setValue(D5LOC);
    e.range.setValue("TRUE")
  }
}
