Want total price in default view when quantity is increased

Hi,

There is no mechanism for this.
You'll have to implement some javascript code to dynamically calculate and display the total price.
For that, you'll want to implement the event quantity.checked :

And you can add your JS in the product / show_default.php view file.
You might also want to implement the hkContentChanged event so that when a new variant is selected via the characteristic selectors, or an option is changed, your JS will be able to recalculate and redisplay the new total price.

This will probably require dozens of javascript lines of code, so you need to be quite proficient in javascript to be able to do that.
