I want to populate the Discnumber tag from a string in the directory name.

e.g.

If directory = 'Greatest Hits' then Discnumber = 01  
If directory = 'Greatest Hits CD1' then Discnumber = 01  
If directory = 'Greatest Hits CD2' then Discnumber = 02  
If directory = 'Greatest Hits CD3' then Discnumber = 03

etc.

I think I need to use an Action, probably Format Value but I'm not sure what to enter in the Format String field.

Please can anyone help?
