getting last entry in database table

I have a table containing steps toward solving a problem. I want to pass the last entry to another database as a solution. How do I do this? What I've tried today is: <? if (isset($cmdAddtoKb)) { // If I want to move the solution do ... $querykb ="SELECT e_description FROM events WHERE t_id = '$t_id';"; $resultkb = mysql_query($querykb, $mysql_link); $answer = mysql_fetch_row($resultkb); $teststring = current($answer); // set up a teststring if empty we are //outside array. First entry is //never empty while ($teststring != "") { //while we are inside the array $kb_answer = $teststring; //pass the current string to the final //variable next($answer); //go to next string in array $teststring = current($answer); //give testvariable new string } What happens is that the while-loop never seems to loop at all. I don't get any errors but it simply doesn't assign entry number 2 to $teststring. It's stuck at entry number 1 (setup outside the loop). I'm missing something obvious again. What? TIA Martin S.
