Sum price in subtitle (list view)

My products on google sheet, when web1.get, add product to list view (quantity products is random)
When list view long click remove "get positoin"
How to calculate the price of the remaining products (prices are in the subtitle column)
Thank you

Can you put an example of your listview ?

when i remove product, it dont calculate, it just get position

You mean something like this ..?

Post a screenshot of your blocks

Also I noticed that same question is asked in Kodular's community.

So you use Kodular and not AppInventor. Maybe a @moderators must close the topic

because that's the idea, mit app inventor i haven't found block long click remove item, i just want to test block, can u show me ur block or aia, thank you very much
