hello. how can we show the field "posted_by" into the seller details or listing details page? More precise the "Dealer" or "Buyer", based on the type of membership chosen by the user when he created the account

in profile, the value shows via <tr>
<td class="name">{$lang.account_type}:</td>
<td class="field">{$profile_info.Type_name}</td>
</tr>

but that is not working in listing details page. i tried to change it into anything that crossed my mind with no success.

thanks
