Hello there,  
I have been trying for 4 hours now to use the insert node. Uploading a .dyn file and an image to illustrate my issue.  
At this point I am a bit tired and disappointed that I can’t get it to work and am thinking about giving up on this.  
Any help is appreciated.

I usually reach for Python for this sort of thing:

```
lists = IN[0]
values = IN[1]
indexes = IN[2]

out = []
for list, value, index in zip(lists, values, indexes):
	for v, i in zip(value, index):
		list.insert(i,v)
	out.append(list)
OUT = out

```

Hope this helps,  
Thomas
