After looking through everything, I just need someone to help me with a sample file (which is a lot to ask for! I know!)
Basically, I will add a button to my layout that starts a script (HUGE THANK YOU to LaRetta)
It'll do one thing.
Insert from Device (QR Code) a numerical value that's unique to each record.
Bring up that one, that's all.
Once you tap the "Quantity" it'll bring up the script that LaRetta showed me how to make.
But above that, is there any good developers/sites who could look into doing this.
