How to calculating values from a text file?

I am new to rhino so please bear with me.
I am running honeybee simulation which is outputting 2 text file. I bring these into rhino. As seen in picture 3, the file is structured as “Month Day Time Radiation1 Radiation2 …”.

All I want to do is sum these Radiation values for whole year (i.e. as output I will get 1 value).


Currently your reading a space-separated text file. You can use Split (“Split Text”) to split the lines into individual values.
