Series

Hello guys,

i'have a very strange situation with the "series" component :

you can see in the attached file Rhino + Grasshopper that  the series of the ribs doesn't work normaly : only the final number of the list is considered by the series.

i cheked everything and there no visible reason for this trouble.

It would have to work but it doesn't...even cooking with trees.

Thanks for your help.

Pierre.
