Table that changes as different attributes are selected

[Lordkelsi]

Hi there, operating on ARC 10.8.2

i have an attribute table with a list of towns, each town as a “voter total” associated with it

i would like to have a table, or graph, or even just a text box that updates real time the total # of voters for the selected town. 
so if I add a selection, it will automatically add that voter total to the sum, or if I remove a selection, it would subtract that voter total from the sum.

Any advice would be super appreciated.

thanks!!

"Updates real time" is tricky in an interface that doesn't support parallel processing. This is less a Data Management issue than an ArcMap one. The ArcGIS Pro interface would let you do this easier (and that isn't a Data Management issue either).

I'm not clear what you mean by "add a selection," but it seems like this isn't a real-time issue, per se, and you're really looking for a script tool that interacts with a UI (which is doable in either interface, and doesn't have a significant Data Management component).
