Rules and Expressions with Open Weather API

Well, I think it is set up, but I can’t get it to evalute the variables. Here is my rule flow

I added all the excludes because the reponse included everything. Even with the excludes, the excluded stuff is still being received.

I am setting two variables. After the script runs, they evaluate to NaN, which I assume is Not a Number.

Any thoughts on what I am doing wrong?
