Help with Python Scripts

Discussion created by starksmr2 on Oct 19, 2011
I have seen this done on a client's GIS Program by ESRI.  I need to develop a script that will allow a user to select on a feature class (msd_sewer) and select all connecting lines upstream and also select all connecting lines downstream.  There should be two radio buttons on the menu bar, one for upstream and one for downstream.
It would be super nice if the selection could reveal any other features that are on or near the selected line.
Does anybody have any ideas where I can start?
