Calculated Fields AppBuilder

Does anyone know how to enable user editing on a calculated field in a browse widget? I have the following calculated field in the expression editor:


I want the user to be able to change the quantity outputted to this field so they can run off labels despite the calculation quantity.

Also it gives me an error saying that I need to have a named field with the format "@ <field-name>" - does anyone know what I am supposed to do here? I'm guessing its an easy fix but I'm not as familiar with AppBuilder

Thank you in advance!

I have never tried enabling a calculated in the AppBuilder so can not advise, but this Progress article may be what you are looking for:

It really does not make any sense to enable a "calculated field". As the field does not have a name you cannot reference it in any way (enabled or retrieve the values that have been entered by the user).

I suppose the only solution is - if your browse is showing temp-table fields you can simply add a new field for the calc field and then enable it.
