Like this:
<cfset grandTotal = 0 >
 
<th>Your Shopping Cart</th>
  <th>Value each</th>
  <th>Colour</th>
  <th>Size</th>
  <th>Qty</th>
  <th>Subtotal</th>
</tr>
<cfloop query="getCart">
  <tr>
    <td>
   	#getCart.item_name#    </td> 
    <td>#getCart.amount#</td>
    <td>#getCart.on0#</td>
    <td>#getCart.on1#</td>
    <td>
      <input type="hidden" name="item_number" value="#getCart.item_number#" />
      <input type="text" size="3" name="quant_#getCart.item_number#" 
           value="#getCart.Quantity#" /></td>
    <cfset itemTotal = getCart.amount * getCart.Quantity >
    <cfset grandTotal = grandTotal + itemTotal >
    <td align="right">#NumberFormat(itemTotal,"0.99")#</td>
  </tr>
 
 
</cfloop>
<tr>
    <td colspan="4">&nbsp;</td>
    <th>Total:</th>
    <td align="right">#NumberFormat(grandTotal,"0.99")#</td>  </tr>
</table>
<input type="hidden" name="doaction" value="updateCart" />
<input type="submit" name="submit" value="Update Quantities">
