need help with code

Hello

I have this code bellow wich is a part of a script on my page. I wanted to edit the size of "First" And "Pevious" once they are displayed onto the site and tryed to add "<font size="4">" but then i get Parse error: syntax error, unexpected T_LNUMBER, expecting ',' or ';' in /public_html/side.php on line 93

How can i change the size of "First" And "Pevious" without the code breaking ?

 

echo '<a href="'.$_SERVER['PHP_SELF'].'?pagenum=1&tag='.$_GET['tag'].'" class="nextprev">&lt;&lt;-First</a>';
echo " ";
$previous = $pagenum-1;
echo '<a href="'.$_SERVER['PHP_SELF'].'?pagenum='.$previous.'&tag='.$_GET['tag'].'" class="nextprev">&lt;- Previous</a>';

PHP:

Next in the BODY part declare some CSS:

<style type="text/css">
  a.nextprev {
    font-family: arial, verdana, sans-serif;
    font-size: 20px;
  }
</style>

Code (markup):

Two things:
1. I couldn't see any </a> to close the anchor.
2. If you're going to display < and/or > on the screen use &lt; and &gt; respectively.

 

i added what you said into the body tag but nothing happend :/ it didint work.

 

add style=\"font-size=4;\" in your a tag
good luck
