As title explains, I am wanting to use Format Value action to bring BPM (%bpm%) and Key (%initialkey%) together in the Grouping (%contentgroup%) field.

However, bpm comes up as e.g. "00103 BPM" and I am only wanting to return the "103"; or if it was "00097 BPM" I want "97".

So I am wanting to do this:

BEFORE:  
Grouping- (nothing or something)  
BPM- 00103 BPM  
Key- 5A

AFTER:  
Grouping- 103-5A

Thanks in advance

I would proceed as follows:  
Format value for field %contentgroup%  
Format string: %bpm% %initialkey%

Replace action for field %contentgroup%  
Search: BPM  
Replace with: -  
(juggle a little bit the the blanks around BPM to get the result just right)

Replace action with regular expression:  
search string: ^0  
replace string:  
(nothing, leave empty)

You can use the Mp3tag converter "Tag - Tag" or the action "Format value".

 

**Convert** | **Tag - Tag** | **ALT+5**

 

Field:  
**CONTENTGROUP**

 

Format string:  
**$num(%BPM%,1)'-'%INITIALKEY%**

 

Preview  
**103-5A**
