PHP in HTML code

An HTML/PHP code migrated to a different hosting platform seems to behave 
differently. The PHP statements within HTML fields or within tables  does 
not execute

PHP within table:

<tr>
 <td align="left"><?="&laquo;".$_SESSION['scripture_text']."&raquo;"?></td>
 </tr>

This PHP code doesn't print in the HTML page.

PHP within form field:

<input type="text" name="reservation_date" value="<?=$_GET['rdate'];?>" 
readonly="">

This PHP code shows on the page when it shouldn't. The same variable is an 
input and an output in this form:

********************************************

<form name="frm" method="post" action="ins_reservation.php" onsubmit="return 
(submitonce(this) && doValidate(this));">
    <table border="0" width="100%" align="center">
     <tr>
      <td valign="top" width="23%">
       <strong>Your Pledge For:</strong></strong></td>
      <td width="75%">
       <p>
       <?php if($_POST['reservation_date'] != "") { ?>
       <input type="text" name="reservation_date" 
value="<?=$_POST['reservation_date'];?>" readonly="">
       <?php }else {  ?>
       <input type="text" name="reservation_date" 
value="<?=$_GET['rdate'];?>" readonly="">
       <?php } ?>

       &nbsp;<img src="images/cal.gif" 
onclick="cal17.select(document.forms[0].reservation_date,'anchor17','MM/dd/yyyy'); 
return false;"  name="anchor17" id="anchor17">
       <!--<td width="1%">-->
        <?php require("calendar/make_update_calendar.php"); ?>
       </p>

                            <?php if ($totalRows_findme == 0 && 
$_GET['email'] != "") { // Show if recordset empty ?>
                              <span class="style1">Not found. Please enter 
info</span>                              <?php } // Show if recordset empty 
?></td>
      </tr>
    </table>

    <table border="0" width="100%" align="center">
             <?php if ($totalRows_findme == 0) { // Show if recordset empty 
?>
                 <tr>
                   <td class="st1">Email:<span style="color:

                   <td class="st1"><input name="email" type="text"

                     <span style="padding-left: 3px;">
                 <input type="button" name="button" id="button" value="Get

                     </span></td>
              </tr>
              <tr>
                    <td width="34%" class="st1"> First Name:<span

                    <td width="66%" class="st1"><input name="first_name" 
type="text" class="v_required" value="<?=$_GET['fname'];?>" /></td>
                  </tr>

Are there times when the <? statements in HTML code don't execute?
