My Contact form

This is the entire "contact us" code of my forum. i've been told it's missing parts, can anyone help in this matter?

Code:

<td valign="top" width="100%"><form action="contact.forum?action=submit" class="report" method="post"><table class="forumline" width="100%" border="0" cellspacing="1" cellpadding="0" align="center"><tr><th class="thHead" colspan="2">Contact us</th></tr><tr><td class="row2" colspan="2"><span class="gensmall">Items marked with a <span class="obligatory">*</span> are required.</span></td></tr><tr><td class="row1"><label for="subject" class="gen">Message subject<span class="obligatory">*</span> :</label></td><td class="row2"><input type="text" name="subject" id="subject" size="78" maxlength="54" class="post" value=""/></td></tr><tr><td class="row1"><label for="message" class="gen">Message contents<span class="obligatory">*</span> :</label></td><td class="row2"><textarea cols="75" rows="10" name="message" id="message" class="post"></textarea></td></tr><tr><td class="row1"><label for="reg_key" class="gen">Confirmation code<span class="obligatory">*</span> :</label></td><td class="row2 captcha"><table border="0"><tr><td align="left"><div class="captcha-img"><label for="reg_key" dir="ltr"><img src="/antirobot_pic.forum?a=d46dd6e0ad6b529ddb8410150e5a3d63" alt="" /></label> <input type="hidden" name="username" value="" /> <input type="hidden" name="time" value="" /></div></td><td align="left"><input type="text" name="reg_key" id="reg_key" maxlength="5" class="post" dir="ltr" /></td></tr></table></td></tr><tr><td class="catBottom" height="28" align="center" colspan="2"><input class="button2" type="submit" name="submit" value="Send" /><input type="hidden" name="time" value="" /></td></tr></table></form>

Cleaned it up, created a widget, sent & received a message...
it works fine @ test site Contact Form

Code:

<center><table><tr><td valign="top" width="100%"><form action="contact.forum?action=submit" class="report" method="post"><table class="forumline" width="100%" border="0" cellspacing="1" cellpadding="0" align="center"><tr><th class="thHead" colspan="2">Contact us</th></tr><tr><td class="row2" colspan="2"><span class="gensmall">Items marked with a <span class="obligatory">*</span> are required.</span></td></tr><tr><td class="row1"><label for="subject" class="gen">Message subject<span class="obligatory">*</span> :</label></td><td class="row2"><input type="text" name="subject" id="subject" size="78" maxlength="54" class="post" value=""></td></tr><tr><td class="row1"><label for="message" class="gen">Message contents<span class="obligatory">*</span> :</label></td><td class="row2"><textarea cols="75" rows="10" name="message" id="message" class="post"></textarea></td></tr><tr><td class="row1"><label for="reg_key" class="gen">Confirmation code<span class="obligatory">*</span> :</label></td><td class="row2 captcha"><table border="0"><tr><td align="left">
