title: SpreadSheet- google script - how to find text in string using "findText()" method?
body: <p>This is the fragment of my GS. When I run then it returned error "TypeError: text.findText is not a function".
  What mistake I did? thanks..</p>
  
  <pre><code>var text = "Martin test x";
  Logger.log(text);
  var range2 = text.findText("x");
  </code></pre>
  
  <p>I would have expected range value "12" in result.</p>
