    How to display a formvalidation() error in a table cell?

    Hi list,

    I am looking for a long time now about writing the error the formvalidation script founds in the form which consists of table.

    For example if userid or group (first td) id emty (td2) I woul like to display 'Error: empty' in the third td.

    I googled around but could not find a way to do it and alert() is ugly and unclear because I have a lot of validations to do

    Could somebody help?

    It would greatly appreciated.

    The HTML is quite simple:

    <form name="RACF-Access" onsubmit="Validateform()">
    <table border=1">
    <colgroup>
    <col width="15">
    <col width="*44">
    <col width="156">
    </colgroup>
    <tr>
    <th>Description</th>
    <th>Data</th>
    <th>Information</th>
    </tr>
    <tr>
    <td>Userid or group</td>
    <td><input type="text" size="8" name="userid"></td>
    <td type="text" id="e_id"></td>
    <tr>
    <td>Autority</td>
    <td><select name="authority">
    <option value="CHECK">CHECK</option>
    <option value="READ">READ</option>
    <option value="UPDATE">UPDATE</option>
    <option value="CONTROL">CONTROL</option>
    <option value="ALTER">ALTER</option>
    <option value="EXECUTE">EXECUTE</option>
    </select>
    </td>
    <td><DIV name="a_autr"</DIV</td>
    </tr>
    <tr>
    <td>Class</td>
    <td><input type="text" size="8" name="class"></td>
    <td><DIV name=e_class"</DIV</td>
    </tr>
    <tr>
    <td>Resource</td>
    <td><input type="text" size="44" name="resource"></td>
    <td><DIV name=e_resource</DIV</td>
    </tr>
    </table>
    <p><img src="./images/jan Einst.Neubauten.jpg" alt="Einst. Neubauten" widtr="159" height="156" align="middle"/></p>
    <input type="submit" value="Check Access">
    </form>

    	skipped='submit,reset',
    	isvalid=true;
    if(!valf.ret){valf.ret={};}
    for(var i=0; i < len; i++){
    if(skipped.indexOf(elems[i].type) !=-1){continue;}
    else{
    var td=document.getElementsByName(elems[i].name)[0].parentNode.parentNode.cells[2];
    td.style.color='#fff';
    td.style.textAlign='center';
