<form method="post" action="insertscore.php" name="csscheckbox" id = "csscheckbox">  <?php $query = "select * questions (`topics` = '.net' or `topics` = 'php') order rand() limit 5"; $result = mysql_query($query);  if ($result && mysql_num_rows($result)) {     $numrows = mysql_num_rows($result); $count =1;  while ($row = mysql_fetch_array($result))  {  ?>  <div class="group">  <input type="hidden" name="<?php echo $row['key_id']; ?>"><?php $row['key_id']; ?></input> <span class="test_question"><strong><?php echo $count;?>) <?php echo $row['question']; ?> </strong><br />  <?php   if($row['answer1'] != null){ ?> <input type = "radio" name="answers" value="<?php echo $row['answer1']; ?>" id="chklimit_1" ></input> <label for="chklimit_1" ><?php echo $row['answer1']; echo "<br />"; } else {} ?></label>   <?php   if($row['answer2'] != null){ ?> <input type = "radio" name="answers" value="<?php echo $row['answer2']; ?>" id="chklimit_2" ></input> <label for="chklimit_2" ><?php  echo $row['answer2']; echo "<br />"; } else {} ?></label>  <?php   if($row['answer3'] != null){ ?> <input type = "radio" name="answers" value="<?php echo $row['answer3']; ?>" id="chklimit_3" ></input> <label for="chklimit_3" ><?php  echo $row['answer3']; echo "<br />"; } else {} ?></label>  <?php   if($row['answer4'] != null){ ?> <input type = "radio" name="answers" value="<?php echo $row['answer4']; ?>" id="chklimit_4" ></input> <label for="chklimit_4" ><?php  echo $row['answer4']; echo "<br />"; } else {} ?></label>  <?php   if($row['answer5'] != null){ ?> <input type = "radio" name="answers" value="<?php echo $row['answer5']; ?>" id="chklimit_5" ></input> <label for="chklimit_5" ><?php  echo $row['answer5']; echo "<br />"; } else {} ?   ></label>  <?php   if($row['answer6'] != null){ ?> <input type = "radio" name="answers" value="<?php echo $row['answer6']; ?>" id="chklimit_6" ></input> <label for="chklimit_6" ><?php  echo $row['answer6']; echo "<br />"; } else {} ?></label>  <?php   if($row['answer7'] != null){ ?> <input type = "radio" name="answers" value="<?php echo $row['answer7']; ?>" id="chklimit_7" ></input> <label for="chklimit_7" ><?php  echo $row['answer7']; echo "<br />"; } else {} ?></label>   <?php   if($row['answer8'] != null){ ?> <input type = "radio" name="answers" value="<?php echo $row['answer8']; ?>" id="chklimit_8" ></input> <label for="chklimit_8" ><?php  echo $row['answer8']; echo "<br />"; } else {} ?></label>  <input type="hidden" name="<?php echo $row['right_answer']; ?>"><?php   $row['right_answer']; ?></input> </div> <input name="submit" type="submit" value="submit answers" class="submit">  </form> 

code on submitted page looks like:

<?php  if(isset($_post['submit'])){  $key_id=$_post['key_id']; echo $key_id;  $question=$_post['question']; echo $question;  $answers=$_post['answers']; echo $answers;  $correctanswer=$_post['correctanswer']; echo $correctanswer;  }   foreach($_post $key => $val) { echo "$key --> $val<br />"; }   //var_dump($_post); ?> 

please let me know if not clear or if missing anything....

thanks,

i would:

1. remove comments //var_dump($_post); , move line @ top of code on submitted page.

2. if still don't see anything, think code on submitted page not in file called insertscore.php or such file not in same folder of form page.
