If you would like to embed validator on a cart page, follow these instructions.

2. Change restriction type to be "Section (widget)"
3. Go to "Online store" > "Themes" > "Actions" > "Edit Code".
4. Here you would need to find a file which represents your cart template. Depending on theme, it might change. Following file location is on out of box shopify theme. If you couldn't find it at same location then best is to contact your theme developer. If you don't get any support from them, feel free to contact us.
