I have a few expressions set up in some user library fields to build file paths and filenames for the Rename, Move, & Copy Files feature.

I am having a problem with the FirstNoEmpty() function in RM&CF. I set up a working custom view with the following expression:

Code: [Select]

Clean(Left(FirstNotEmpty([Artist Sort], ListItem([Artist],0), NO ARTIST!),30),3)
This is part of the filename expression of

Code: [Select]

if(IsEmpty([Disc #],1),FIX DISC NUMBER!,padnumber([disc #],2))-if(isempty([Track #],1),FIX TRACK NUMBERS!,padnumber([Track #], 2)) - Clean(Left(FirstNotEmpty([Artist Sort], ListItem([Artist],0), NO ARTIST!),30),3) - Clean(left([Name],50),3)
This view parses that filename expression correctly, but when I try using the same expression in RM&CF, I get an "Unknown Artist Sort" where the artist show be (The first expression above).

I've included a screenshot for reference.



The Location Test custom view and the RM&CF dialog are both using the same variable with the expression above for the filename.

OK, I see why Unknown Artist Sort is being displayed in Rename, Move & Copy in contrast to the custom view.

I still don't understand (I know I'm dense) why the FirstNotEmpty() function isn't working correctly. It should first check [Artist Sort] for content, if empty it should check ListItem([Artist],0), which would be the first item in the Artist field list, and if THAT is empty (unlikely), display NO ARTIST!.

Does FirstNotEmpty() not work correctly in filenames?

[Artist Sort] is also subject to display output in RM&C.  Have you changed it to [Artist Sort,0] ?

Ok, that worked. I wasn't aware that I could put a variable into raw mode like that. I thought that was only possible using the Field() function -Field(Artist Sort,0).

Thanks, I've been racking my brain on this all weekend! 

[MrC]

Have a quick re-read of Fields.

Don't think of [field] as a variable.  Stock fields and user fields - they are all just fields.

Yes, you are correct. I misspoke. I meant I wasn't aware I was able to put the abbreviated form of [Album Artist] versus Field(Album Artist) into raw mode like you stated.

Thanks again for your help!

Now if only the expression editor could retain formatting correctly...
