I bet if you used the debugger tools included in the browser you would see some exception along the lines of Undefined variable [andr]

Basically your function is calling for it (andr) as a variable; instead of a string

HTML

<script type="text/javascript"> 
function stringWord() {
  //  document.getElementById(andr).innerHTML="os";
  document.getElementById("andr").innerHTML="os"; 
}</script>
