Invalid Barcode

[Clark_Bentley]

I am having issues and need help!

Ok so I may be doing this incorrectly but it is not showing any errors?

So I want this:

• to scan a barcode and be able to update inventory
  -I have product ID’s which correlate with Barcodes that i generated from Free Online Barcode Generator: Code-128
• I have a line for Barcode and the current code I have is “https://zxing.org/w/chart?cht=qr&chs=350x350&chld=L&choe=UTF-8&chl=”&[Item ID] (line is set to Image and scannable)

When i am testing it out i have the barcode pulled up on my computer and i scan it within the app and it says its invalid?

What do I do?

Also how do I make a view that only allows you to scan barcode and automatically brings up the Inventory in and out screen?
