I added the following code into my liquid and check out using these instructions:

Here is what I want:
Only have the pixel fire/trigger when customer actually reach the final checkout screen (after they click purchase). This is assuming the customer adds item(s) to cart, clicks Next, and reaches the final checkout page. What I did above does not do what I intend. It actually fires the 'add to cart' when someone views the product according to FB helper extension. From my research this varies depending on one's theme.
Looking for someone to sort this out.
