Can't create polyline

Hi, I'm new using Grasshopper.

I am trying to create a polyline between six points to form a hexagon (i don't want to use de polygon command because i'm just practicing).

The problem is that when I connect the first vertex, and then I try to connect the second one, the first vertex disconnects and a warning appears with the text "1. Input parameter V failed to collect data".

I don't know what I'm dping wrong, can somebody help me?

I attach a picture of the problem, and the link of the tutorial i'm following (Minute 6:00)

I believe you skipped some of the early tutorials to get to the visually interesting ones. :-)

to connect many wires in one input, you have to press and hold shift until you finish the wire connection.you will see a plus sign with the arrow turning green that informs you that you can make multiple wires connection.

along with the videos it is advised to have the pdf primer open. it answers all these fundamental questions.
