Programatically call total sales by item?

I’ve been looking at the code in the addon and I see the function I want to call:
awts_get_total_sales_per_product($product_id ='')

But I don’t know how to call it from my little shortcode function.

What do I have to include in my function to be able to refer to that method?

Edit:
As I’m reading through your functions, I’m not sure if that’s actually the function I want to call.
What I want is what I’ve stated in the original question. A function where I call it with a product id as the argument and I receive the earnings that that product has accumulated. I know it already exists in some capacity because you display the product’s earnings in the back end on the edit product page.

Due to the inactivity of the support mod and the urgency of my completing this design I took the function I needed from the plugin and pasted it into my own code so I can call the function as I need.

I was correct in assuming that awts_get_total_sales_per_product($product_id ='') was the right function. It returns the total ‘number’ of sales as well as the total sales for the product.

I wrote out my answer more in depth on my Stack Overflow question.

Sorry for late response.Really happy to know that you had found the solutions.
