I wanted to change my album titles from:

Coast To Coast AM Aug 2 2010

to

Coast To Coast AM Aug 02 2010

I've done this by using Replace, i.e:

Replace "ALBUM": "2" -\> " 02 "

I'm sure there is a muck quicker way to do this for all numbers 1-9. Have tried various ways including

$num([1-9],2) in a format value

Can't figure out where i'm going wrong!

Any help appreciated.

_Action type:_ **Replace with regular expressions**  
_Field:_ **ALBUM**  
_Regular expression:_ **" (\d) "**  
_Replace matches with:_ **" 0$1 "**  
(without quotes)

Many Thanks!

I had tried

Regular expression:" (\d) "

But I was then unsure about what to use for the replace matches!
