woocommerce integration

Hi,

I just tried out the woocommerce add-on, but can’t get it working all the way.

I connected the form to a woocommerce via adding form and fieldnames inside the “edit product” in woocommerce

On the front-end of my webpage I added a woocommerce add to cart button called “l?gg i varukorg” and a woocommrece product price display just above the add to cart button. The price calculated in the form matches the price that the woocommerce price display shows. So far so good.

To reveal the calculated form on my page you:
1. add a number in the field called “storlek p? bostaden (kvm)”
2. Select a radiobutton in the field called “typ av stad”
3. Then you can click the button “ber?kna pris” and a calculated price gets revealed.

But then when I click the “add to cart” button, the page goes white and says “the form is empty”

I use the divi theme and added a html content field inside my form with the code:
<script>
woocommerce_price_selector = ‘.custom-price-tag’;
</script>

Am I missing something or done something wrong?

The page I need help with: [log in to see the link]
