I'm convinced I'm missing something very basic and I thank anyone/everyone in advance for any guidance.
I have a simple table (components), that lists individual components and the count of each component in inventory.
Scenario: User is presented with the app screen below, selects the specific component for which they'd like to add inventory (from $[Picklist]) and inputs the quantity of that component to be added to the inventory. I'd like to take the value from $[Component Quantity] on this screen and ADD it to the existing value of [Component Quantity] for the specified component within the components table.
I cannot seem to determine the correct formula for this overwrite operation.
I welcome any and all guidance, or alternative means to achieve a similar result.
