Uncaught ReferenceError

[geatzo]

im getting this error

 

Uncaught ReferenceError: changeAvi is not defined
    at HTMLSelectElement.onchange

 

I have the script working on another website which works fine ive simply tried to add it to my new website and getting this error

 

I have the script at the top of the page
      

 <script src="http://code.jquery.com/jquery-1.10.2.js"></script>
<script src="http://code.jquery.com/ui/1.11.2/jquery-ui.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>
    <script src="https://pkmnhelios.com/membersarea_files/button.e7f9415a2e000feaab02c86dd5802747.js.download"></script>
<script src="exponential.js"></script>
  
     <script type="text/javascript">
 function changeAvi(){
     var image = document.getElementById('avatarchange');
     var dropd = document.getElementById('Avatar');
   image.src = dropd.value;
     };
 </script> 

<br>
 <input type="submit" name="update" id="button"/> </form>

<p>
  <script type="text/javascript">
 function changeAvi(){
     var image = document.getElementById('avatarchange');
     var dropd = document.getElementById('Avatar');
   image.src = dropd.value;
     };
 </script> 

 

 

Then i run some php

 

 

oose your avatar <br><?php     echo '<img id=avatarchange src=images/trainers/000.png />'; ?>
                   <?php
     echo '<select name="avatar" id="Avatar" onChange="changeAvi()"">';
      $sql6=mysqli_query($link,"SELECT * FROM avatars");
     while ($row6=mysqli_fetch_array($sql6)){
     echo "<option value='".$row6['Image']."'>".$row6['Name']."</option>";
         ?>
    
    <?php
         
         
      }
     echo '</select>';   

 

And yes im gonna update it to pdo  again this script works on another page inside my site but not a blank page

Strange a function that is defined twice should be flagged as "undefined".

You have a surfeit of quotes in this line...

echo '<select name="avatar" id="Avatar" onChange="changeAvi()"">';
                                                              ^
