store the needed data in an array that's later used to populate your shopping list display.
Thanks for the suggestion, I will head in that direction.
I am somewhat familar with arrays, but not completely understand them yet.
I am looking to do something similar to this:
When the user click on the "Add to Shopping List' it adds the specific item they selelcted, Then if they click on the shopping list tab, it will show all the selected items. Are they using arrays to accomplish this? And can you tell me what kind of component they are loading the info into and how you go about linking the array to load into that specific component when the button is clicked? Thanks!
yes, they're almost certainly using arrays in that app.
from your questions, you don't have the background in programming needed to create a shopping cart application. you should either hire someone to do this for you or, if you want do it yourself, start with smaller projects so you can advance from a beginning developer to an advanced developer.
