@Jake_S- Good morning, Jake.
This is what happens. I go in to make a polygon in the Web AppBuilder - I'm not using Experience Builder right now as it does not have the edit widget adequately functioning - and as I double click to finish making the polygon a table opens up for me to enter the attribute values. I begin by entering the EstbYear and other information that is relevant to the next calculation and once I do that, close the attribute table and go to the layer widget to uncheck and check back the layer in question as this refreshes the layer both the 'Age' and the other 'field' get populated , which is what I wanted.
However, before your helpful hints that was not happening the 'Age' would get populated but the next calculation would not until I went back to the 'Age' field and re-added the age again.
With your helpful hints, I went to the Attribute Rules window in ArcGIS Pro and reordered the 'Age' field to get populated first before the next calculation and that did it.
Hope this helps, Jake. Please let me know if you need further explanation or, you need to connect with me to see it. I will be glad to show you my process.
Thank you,
Abi
