How to calculate the price of the remaining products (prices are in the subtitle column)

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
