title: php Form calculater how can i fix this
body: <p>OK i am making a form that calculates line 1+ line 2 +*.01% then adds line 3+ line 4 then gives a total. I am having a problem with *.01 it works with just the first two but when i add the last two it drops one line if i take it out all four add fine.  </p>
  
  <pre><code>&lt;?php
  if (count($_POST) &gt; 0 &amp;&amp; isset($_POST["calc15TextArea2"])){
      // add First and Second Numbers
      $sum = $_POST["indexEditbox1"] + $_POST["indexEditbox2"]*.01+ $_POST      ["calc15Editbox3"] + $_POST ["calc15Editbox4"];
      // their sum is diplayed as
      echo "Total is $ $sum";
  }
  ?&gt;
  </code></pre>
