Hello. How do I setup an action to check if the DISCNUMBER field is blank, and if so replace it with "1/1" ?

I tried using the REPLACE type, but I can't leave the Original field blank. Ideas?

Cheers,  
DJ

Action: **Format value**  
Field: **DISCNUMBER**  
If tag-field DISCNUMBER does not exist ...  
Formatstring: **$if2(%DISCNUMBER%,'1/1')**  
If tag-field DISCNUMBER does not exist or contains space characters ...  
Formatstring: **$if($neql($trim(%DISCNUMBER%),),%DISCNUMBER%,'1/1')**  
... or ...  
Formatstring: **$if($eql($trim(%DISCNUMBER%),),'1/1',%DISCNUMBER%)**
