Change free text sorting - OTRS ITSM

[jj99]

Hi I want to show free text fields in Change overview , I edited the AgentITSMChangeOverviewSmall.dtl file and added code for change free text.
Change free text field is visible in Change Overview but I am enable to sort as we can do with other attributes.

Here is my code:

Code: Select all

 <th class="ChangeFreeText1 $QData{"CSS"}">
    <a href="$Env{"Baselink"}Action=$Env{"Action"};$Data{"LinkSort"};SortBy=ChangeFreeText1;OrderBy=$LQData{"OrderBy"}">$Text{"ChangeFreeText1"}</a>
    </th>   

   <td>
   <div>$Text{"$Data{"ChangeFreeText1"}"}</div>
   </td>

Can someone tell me whats missing in my code.
