i need to add number to variable like in simple javascript:
var a = 100
var b = 200
var c = a + b
but in shopify liquid code:
{% assign total_price = cart_price + shipping_price %}
i have following error
how to fix it
you can try converting the variables into integer, you can defined this by doing
{% liquid
assign cartPrice = cart_price | plus: 0
assign shippingPrice = shipping_price | plus: 0
assign total_price = cartPrice + shippingPrice
%}
