Connect coordinate points(xyz) with a curve/line

need your suggestion/help to connect the dots

can you show the errors on the yellow nodes?

“Warning: Asked to convert non-convertible types”
error message to both nodes.

can you check if all your values are double (not string)

the last item on the list is “null”

use the drop item nodes, nulls will give errors upstream in your workflow

please bear with me …i am a newbie…i will try to wokout your advise. could you explain
in detail

thank you very much for your time…

do you still need help?

still studying your suggestion…

was able to drop the “null” item…I will proceed the flow…i will come back to you once i hit the wall again…again…thank you very much…it was a great help.
