Help with syncing a data value to sheets backend

[Humza_Khokhar]

I need help with an inventory app I am using from a sample found here

There is a “current stock” value that is calculated but kept as a virtual column, only shows the value on the app. I want to display that value on my google sheets backend and update the product list quantity of an item every time the stock changes.

There was a link in the comments to google plus forum where this question may have been asked, but that is now dead.
