I would like to grant user points to product owner in amount of product price after product sold.
for this I define a rule as below:

Events:
• Completing the checkout process

Actions:

• Loop (commerce-order:commerce-line-items)

and define a Rule component as below:

Conditions:
• Entity has field (Entity: commerce-line-item, Field: commerce_product)

Actions:

• Grant points to a user: (User: commerce-line-item:commerce-product:creator, Points: commerce-line-item:commerce-product:commerce-price:amount)

But when I save component it makes error:

Error message
Data selector commerce-line-item:commerce-product:commerce-price:amount for parameter points is invalid.

How I can do that?
tnx
