How can I add an extra cost selection to the cart total on my ecommerce site?

[ghuerta]

Hi!

I am needing to implement a functionality in which on the cart page, through a checkbox, select or similar, it is possible to add a cost that is added to the total of the order. For example: If the total of the order is 100, there is a checkbox or select that allows you to add 10, another 20 and so on ...

I am not finding a way to access the order amount from the cart file, and then add the extra cost there.

Could someone give me a hint?

Thanks!
