Showing error on other part of page

[toplisek]

I have the following code which I would like to show with variable or function.
How to do it?

Code is the following:

 {
    ?>
  <div class=clear></div>
  <div class="fl_left"  style="padding-left: 40px;">
  <ul class="error">
  
    <li>This <b>E-mail</b> is already in use. Please try another e-mail.</li>
  </ul>
  </div>
  <div class=clear></div>
  <?
    }
