Evaluator: filepathdest confuses Copy AS

Help & Support
1

All these work:

Copy AS=newname.txt
Copy AS={="newname.txt"=}
Copy AS="{="newname (" + FilePart(filepath) + ").txt"=}"
Copy AS="{="newname (" + FilePart(source) + ").txt"=}"
Copy AS="{="newname (" + FilePart(dest) + ").txt"=}"

This creates the correct command in the log but does not work (won't run):

Copy AS="{="newname (" + FilePart(filepathdest) + ").txt"=}"

It can be made to work like this:

Copy FILE={filepath} AS="{="newname (" + FilePart(filepathdest) + ").txt"=}"

Seems odd.
