Checkboxes in php

[Lesane]

I try to determine if a variable is set and if so then the checkbox is selected. I tried it with this code but it dont works, when i execute it then all the checkboxes are checked while only one field is filled with aw so 1 checkbox has 2 be checked instead of all

PHP Code:

$result = mysql_query("SELECT aw,awardsid,name, url FROM award");
         while ($award = mysql_fetch_array($result)) {
         
         if (Isset($award[aw]))
         $lala="checked";
         else
         $lala="";
         
       echo "<tr><td><input type='checkbox' name='aw[$award[awardsid]]' value='$award[awardsid]'";
          if ($aw) {
          echo "selected $lala>$award[name]</td><td nowrap>";
          } else {
          echo " $lala>$award[name]</td><td nowrap>";
          }
       echo "<img src=\"$award[url]\">&nbsp;&nbsp;&nbsp;</td>";
     } 


As you can c, i'm using this code to check if its set or not:

PHP Code:

if (Isset($award[aw]))
         $lala="checked";
         else
         $lala=""; 


Hope someone can help me out, any help is appreciated.
