I'm trying to apply this script to a specific tab to not ruin all the other tabs.

function onEdit(e) {

  let range=e.range;
  let activeRow = range.getRow();
  let activeColumn = range.getColumn();
  let cellValue = range.getValue();
  let sheet = SpreadsheetApp.getActiveSheet();

    if (activeColumn == 9) {

      if (cellValue == false) {


      } else {

          sheet.getRange(activeRow,8).setValue(new Date());

Use Sheet.getName(), like this:

function onEdit(e) {
  if (e.range.columnStart !== 9
    || e.range.getSheet().getName().match(/^(Sheet1|Sheet2)$/i)) {
  e.range.offset(0, -1)
    .setValue(e.value === 'FALSE' ? null : new Date());
