[RESOLVED] Unexpected T_ELSE on line 42

[BrailleSchool]

Further to my thread here: http://www.vbforums.com/showthread.php?t=398545

I have inserted the following code and I am getting an error. What am I doing wrong? Totally a newb to PHP and would love to learn this language.

<?php if ($clientVersionString = $currentVersionString) ?>
    <table><tr> 
      <td>You currently have the current version installed on your computer.</td> 
    </tr>
<?php else: ?>
    <tr> 
      <td>A new version is available for download.  Please login to your BrailleSchool account to download the new version.<br><br>

To upgrade to the new version, UNINSTALL your current version before installing the new version.  If you are upgrading to a completely new version, for example, from 1.x.x to 2.x.x then there is an upgrade price of $4.99 applicable before a new licence will be issued.<br><br>
<b>To uninstall:</b><br>

Click START-> CONTROL PANEL. Double click Add/Remove Programs. Find Braille Reference Guide and REMOVE it. Do NOT "repair" or "change".<br><br> 

Then download the new version and install it. If you are prompted to REPAIR or REMOVE instead of install. You should select REMOVE and then download the file again and install it.</td> 
    </tr></table>
<?php endif; ?>

The complete code is as follows:

<?php 
include("config.php"); 

$connection = mysql_connect($server, $brlqrg_un, $brlqrg_pw); 
mysql_select_db($brlqrf_db, $connection); 

$query = "SELECT CurrVer FROM CurrentVersion"; 

$clientVersionString = $_GET['Version']; 

$result = @mysql_query($query, $connection); 
if (is_resource($result)) { 
  $currentVersionString = mysql_result($result, 0); 
  $majorDiff = $currentVersionString[0] - $clientVersionString[0]; 
  $minorDiff = $currentVersionString[1] - $clientVersionString[1]; 
  $revisionDiff = $currentVersionString[2] - $clientVersionString[2]; 
} 

?><table> 
  <?php if (is_resource($result)): ?> 
    <tr> 
      <td><b>Current Version:</b></td>
      <td><?=$currentVersionString?></td> 
    </tr> 
    <tr> 
      <td><b>Installed Version:</b></td>
      <td><?=$clientVersionString?></td>
    </tr>
    <tr>
      <td colspan="2">You are <b><?=$majorDiff?>.<?=$minorDiff?>.<?=$revisionDiff?> versions out of date.</td> 
    </tr> 
  <?php else: ?> 
    <tr> 
      <td><b>Unable to retrieve the current version</b></td> 
    </tr> 
  <?php endif; ?> 
</table>
<?php if ($clientVersionString = $currentVersionString) ?>
    <table><tr> 
      <td>You currently have the current version installed on your computer.</td> 
    </tr>
<?php else: ?>
    <tr> 
      <td>A new version is available for download.  Please login to your BrailleSchool account to download the new version.<br><br>

<?php endif; ?>

Line 42 is the following (<?php else: ?>)

<?php if ($clientVersionString = $currentVersionString) ?>
    <table><tr> 
      <td>You currently have the current version installed on your computer.</td> 
    </tr>
<?php else: ?>
