Resolved myself:
find the code:
Code:
<td class="alt1" align="center"><span class="smallfont">$get_lxt[musername]</span></td>
and change it into:
Code:
<td class="alt1" align="center"><span class="smallfont"><a href="member.php?$session[sessionurl]u=$get_lxt[userid]">$get_lxt[musername]</a></span></td>
