Hello. I am stuck. I am trying to calculate a grand total for a list of Drink products on my delivery app.
I have added the items into my database and when the Plus button is clicked the necessary information is sent to my ‘Shopping Cart’
i a trying to add the Price and Quantity into the list of ‘Shopping Cart’ for a Grand total so the customer can check out and pay.
How can I get the input to calculate the price and quantity?
This has confused me for over 2 weeks now. and I am worried the issue may be some fields in my database. I have attached images of my work.
IF ANYONE CAN HELP EXPLAIN THIS TO ME IN A REALLY DUMBED SOWN VERSION you would be a life saver!!
