Timestamp When Cell Changed to Done

Automatically create a timestamp when a column of cells is changed to "Done" The Timestamp goes into the next column over from the status. This can be edited to look at any column, for any text, and enter a formatted timestamp into any other column on same row as change occured.


function onEdit(edit) {
var row =  edit.range.getRow()
var column = edit.range.getColumn()
var newValue = edit.value
if(column == 2 &&
    row >=2 &&
    newValue == "Done" ){
  var timestamp = Utilities.formatDate(
    new Date(),
