This could help ?

Can Dynamo pull data from a calculate value parameter?

Bill, Here is how i was able to achieve what your looking for. Try using the “code block” node, i always seem to have better results. For some reason it extracted an extra value blank so i had to remove it from the list. The best way i know to add all values of a list together is used Lunchbox tool “Mass Addition” for this you have to convert your area to a Number via String then back to number. Let me know if you find an easier workflow Thanks, William [2015-01-16_18-45-12]
