Changing the cart quantity in Interspire Shopping Cart

The Cart "quantity" dropdown when changed to textbox allows only 2 digits that can be entered. To change this I tried the following:

1. Open the template folder that is being used. You can check in "Store Design" section of Admin about the template that you are using.
2. Go to Snippets and open  CartItemQtyText.html file.
3. Search for "maxlength=" and change the number or remove it.
4. Save the changes made.

Please note that the above steps has to be repeated when another template is used.
