Action: remove fields then, replace fild with custom string

[Flemming]

Hi.
I am able to remove all tags except they I want using the quick action "remove fields except" with ALBUM;ALBUMARTIST;ARTIST;YEAR.

I try to also use the Action group to add fields ALBUM and ALBUMARTIST and assign them with value [no album] and [no album artist], but nothing happens when I run it.
What am I doing wrong?

[no album] and [no album artist]

You use actions of the type "replace" which can only replace a text if is there.
Try an action of the type "Format value" - please note that [and ] are special characters in format strings.

worded!, and I used ' to be able to use [ and ].
