How can I put the error message below input field? I trying to put it this way:

<cms:input name='member_displayname' type='text' placeholder='Name' Label='Your Name' required='1' /><br />
<cms:if k_error_member_displayname ><p class="notice"><font color='red'><cms:show k_error_member_displayname /></font></p></cms:if>

But nothing shows up. How to solve it?
