select same index in all branches

Hi Guys,

Just a quick one..

how to select same index in all branches? let us say I have 10 branches, each has 10 indexes inside.. how to pick index {0} in all branches?

basically i want to extract isocurves from a surface using isocurve component... I use surface divide component to get points to generate isocurves at, but I do have a duplicate isocurve at every point.

For one direction I can list one index using list item, for the other direction need to pick same index from inside all branches.

It looks easy but I don;t know why take me all that time...

Appreciate your help.

cheers
