It did precisely what your sample gave said to do...

(coordinates), look for the node 4, and extract from node 4 the
coordinate (x) and place it on an array nodeax.

Well, that makes no sense from the supposed output below where there's a
0 0 given for element 1 -- there's no 0 0 in the coord array for a node 4.

So, I don't think you've got what you want down precisely yet...

> 2 2 3

...

> Node X Y
> 1 0 0
> 2 2 0
> 3 4 0
> 4 6 0

...

> Elem Nodea Nodeb Nodeax
> 1 4 2 0 0
> 2 2 3 2 0

...

Try again, that doesn't seem to work to me.

Where, again, do you think the '0 0' come from for the first entry, now?
