I have a PHP page that has
 require_once("genMyOverlay.js.php");
 .
 .
 .
 echo "<body>";
 echo "<script language=\"JavaScript\">doit(\"mydiv\");</script><br>";
 echo "</body>";

genMyOverlay.js.php contains: createDiv() (see below) that creates a <DIV
ID="mydiv"> and sets it up to overlay a portion of the wbe page and
doit()starts it off.

invoke the web page once and it works like it should.  invoke the web page a
second time (and thereafter until a new session) and it gets error:
 "doit is not defined"

view the source (at the client browser) and it is identical both (all) times

can anyone please help me understand what is happening?

genMyOverlay.js.php contains
 <script language="PHP">
  echo "<script language=\"JavaScript\">";
  echo "function createDiv()";
  echo " {";
   .
   .
   .
  echo " }";
  echo "function doit(ElementID)";
  echo " {";
  echo " creatDIV()";
   .
   .
   .
  echo " }";
  echo "</script>";
 </script>
