What I am trying to do is enclose disc numbers in brackets

For example  
Disc 1 would become (Disc 1)  
Disc 2 would become (Disc 2)  
Disc 12 would become (Disc 12)  
Disc 20 would become (Disc 20)

I can get Disc 1 to (Disc 1) and Disc 2 to (Disc 2) but when it comes to double digits the whole thing falls in a heap so I need your help please. I work in community radio and this feature is very important for cataloguing purposes

Thanks  
Gavin

Use replace with regular expression action.

Replace.

(?i)(?!\()Disc\s+(\d+)(?!\))

With:

(Disc $1)
