Undefined Index & Undefined Variable Error Messages

Hi i created one updatable add to cart button for each page of my site, as i am selling each product individually from a separate page. Each page that i have tested the add to cart button on is throwing up the same error message below;

"Notice: Undefined index: cocolynnshoppingcart_1_ID_Add in C:\xampp\htdocs\specials1.php on line 56"

"Notice: Undefined variable: ATC_itemQuantity in C:\xampp\htdocs\specials1.php on line 73"

Any ideas how i can resolve these error messages and get the add to cart buttons to work?

I have zipped up one of the pages and attached.

Any help appreciated!

Cheers

</form>

        </div>



<div style="width:86px; float:left;  #00ff00">

  <input type="hidden" name="cocolynnshoppingcart_1_ID_Add" value="<?php echo $row_Products["ProductID"]; ?>" />

  <input type="text" name="cocolynnshoppingcart_1_Quantity_Add" value="1" size="4" />

your ID and quantity elements have been moved outside of the form. change that to:

<input type="hidden" name="cocolynnshoppingcart_1_ID_Add" value="<?php echo $row_Products["ProductID"]; ?>" />

  <input type="text" name="cocolynnshoppingcart_1_Quantity_Add" value="1" size="4" />
