Hi, I created a new custom field to capture the catalog number being provided by Beatport. I am using this as the logic: Name: Catalognumber Value: $meta\_sep(catalog #,\) Field: %catalognumber% I can now see the field with data in it in the main window, however when i try and use that field to change filenames etc, it's coming up as if there is no data in the field. Any help would be appreciate ---

Can you please show us your Format string to change the filename? (The one you use in your action or Convert Tag -\> Filename). Any it would be helpful to see the content of the Extended Tags window (please press Alt+T on one of your tracks and copy & paste a screenshot from this window in your answer). ---

As you can see, there is no `CATALOGNUMBER` tag in your overview of all existing tags. Only a custom `CATALOG #`. You can now use the CATALOG # to rename your files, or adjust your initial logic. What do you prefer? ---

Ok I tested and `m:\Shanti Radio Moscow\%catalog #%\%AlbumArtist% - %Album%\%artist% - %title%` is working, thank you! ---

Just for the record: Your initial logic - using the Convert Tag -\> Tag (showing a preview) - would be: Field: `CATALOGNUMBER` Format string: `%CATALOG #%` ![image](https://community.mp3tag.de/uploads/default/original/2X/b/b3c74231e2086a24435d841dbb5cd3767385b9e7.png) Or as an action: ![image](https://community.mp3tag.de/uploads/default/original/2X/b/b296c501bcd2517a005d507972dcd76f6fced33e.png) Depending on your player (software), your custom `CATALOG #` can not be read or displayed. The more used "official" one would be `CATALOGNUMBER`. ---

> [@Torqpoc](#): > > Name: Catalognumber > Value: $meta\_sep(catalog #,) > Field: %catalognumber% I see something illogical here: You see the contents of %CATALOG #%. But that is a display only. And then you write more or less nothing to CATALOGNUMBER. If you want to update CATALOGNUMBER you would have to use an action or converter as @LyricsLover described. And update the column definition so that it displays and writes the same field: Name: Catalognumber Value: %catalognumber% Field: %catalognumber% ---
