@mzjensen I disagree, being able to do something in Dynamo (even if for you that have already acquired some experience with it, it might seem trivial), enables to connect workflows (e.g. send that total value to Excel, writing it into a text, assign it as a property set, etc. as suggested by @WrightEngineering).
Even the longest walk starts with the first step.
Looking ahead, the capability of extracting a property from similar objects and sum them up is one of many that is required to drive generative design workflows (e.g. select a parking lot configuration that maximises the park stalls whilst minimizing the curbs length).
You make a valid point, LISP could cut it, but where is the innovation in that?
Please, next time do not dismiss too quickly the request of a fellow forum member (especially if it is the first time they manage to collect the courage to post their first question, welcome @bfiebs!), remember where you started from and be mentors, you make a great one.
