Hi,
I have created a zap to create an invoice in quickbooks when I receive a new order in shopify.
I am getting a line item error as follows

Shopify does not total the line items, so I created a zapier formatter step to generate price X quantity as below, and used this as a custom field which is what lots of the other forums suggest.

Also for more detail, I have included my formula, which I understand is the correct way to create a line item

Any help is greatly appreciated in fixing my issue!
