Replacing column header

[Dalmatino16]

Hi, I am trying to use “Insert column header node”, and keep getting this error

Here is the lookup and the new value table

and here is the column I need to rename

here are the node settings

Can someone help me please? What am I doing wrong?

I figured out what I did wrong - I switched lookup and value columns.
