<form action='mandaemail.php' method='post' target='newwin' onSubmit = " window.open('','newwin','width=400,height=290,scrollbars=NO,menubar=NO,resizable=NO,titlebar=NO,status=NO')">
<div align="center"> <span class="link" onClick="submit( window.open('','newwin','width=400,height=290,scrollbars=NO,menubar=NO,resizable=NO,titlebar=NO,status=NO'))" style='text-decoration:underline;cursor:pointer;'><B style="color:#0000FF">mandar correo</B></br></span>
</div>
<input name="p" type='hidden' value='<?=$variable;?>'>
</form>
