Hello everyone. I need help I am not a coder. I tried too many things but it won’t work so cannot find any solution about it.

my website link is > tnsart . c o m /grafik-standart

this is a basic form which is working like a service system with points. (each service has points).
services are to the left “ürün”
points header is “Puan”
quantity is “Miktar”
counting is “Puan miktarı”

this form is working but I wanted add some functions in it.

I have got 3 questions
1-) why should I click elsewhere empty space of the page to see a result while changing quantity values? is there anyway to work without doing it ?

2-) I would like to find a true code for calculate by live all of “Puan Miktarı” which are the total points. When they reach the limit total 500 points it should stop and warn. how could I do that ?

3-) if you cannot help, could you tell me where should I looking for working these systems ? array ? repeating ?

export function total_change(event) at the end of the code and tried to make it calculate all of additions. it won’t working :frowning:

Thanks for your help.
