<?php
  //calculate the area of an equilateral triangle
  function calcTriangle($cVal) {
    $halfSide = $cVal/2;
    $otherSide = sqrt(($cVal*$cVal) - ($halfSide*$halfSide));
    $areaValue = $otherSide * $halfSide;
    echo "<p>The area of an equilateral triangle whose sides are
    {$cVal} is {$areaValue}.</p>\n";
  }
$yeah = (isset($_POST['vfld']))?$_POST['vfld']:'';
    if (isset($_POST['submit'])) {
  if ($_POST['submit'] == "Clear") {
    $yeah = "";
   } elseif ($_POST['submit'] == "Calculate") {
      if (!eregi(square|circle|triangle, $yeah)) {
        echo "<p>Sorry I forgot to mention the the shape needs to be
                a Square, Circle, or a Triangle.</p>".
            "<p>Please return and try again.</p>";
     exit;
      }
}}


?>
<form method="post" action="makingspace3.php"
  id="form1" name=form1">
  <p>
  Write down a shape and a number and I will compute the area for:
  <input type="text" id="vfld" name="vfld"
  value="<?php echo $yeah; ?>"/>
  </p>
<p>
  After you have done this click calcualte to see results
  </p>
  <p>
  <input type="submit" name="submit" value="Calculate" />
  <input type="submit" name="submit" value="Clear" />
  </p>
  </form>

Firstly, eregi is deprecated you should use preg_match instead. Secondly, the first argument to eregi (and preg_match) is a string, strings are surrounded by quotes in PHP.
