Missing linked minimal surface script

hi I got some minimal surface script from old discussions

but when i download script, there are some missing parts


This attached image is normal script taken by the maker

Is that the wrong download?
or Is that because I did not install the add on?
I have grasshopper version august 27 2014 and installed kangaroo 1 , 2 and lunchbox

If anyone can fix this problems, thanks a lot

Millipede for sure. Lunchbox or mesh+?

Just looking at the picture. I would also add to Laurent‘s comment Weaverbird plugin
