title: When i copy a spreadsheet script/triggers don't work
body: <p>I've created a spreadsheet with a <code>onEdit()</code> trigger based in a function called <code>fillvalues()</code> and it works fine.</p>
  
  <p>I need to make several copies of this spreadsheet because it is used to make work reports, but when I make a copy the script doesn't work because the triggers are inactive or it needs authorization to run.</p>
  
  <p>How can I overcome this to copy the trigger function with the new spreadsheet and to ask permission when the spreadsheet open?</p>
