A way to add a 0 to track number?

Hey guys, I am new to this scripting stuff but I am doing my reading and trying to figure it out.
OK, what I would like to do is add a 0 to numerals 1-9 in the track #.

So, if we have 1,2,3,4,5,6,7,8,9,10,11,12..etc for track numbers.

It will modify them to


Any suggestions guys?

Here's two way of doing the same job.

Action #1:

Action type: Format value
Field: TRACK
Formatstring: $num(%track%,2)

Enter in where it says 2 how many leading zeros you want.

Action #2:

Action type: Replace with regular expression
Field: TRACK
Regular expression: ^(\d)$
Replace matches with: 0$1

[ ] case-sensitive comparison

This uses a regular expression in the TRACK field.

^ MATCHES the start of the string
( STARTS capture
\d MATCHES any digit 0-9
) ENDS capture
$ MATCHES end of string.

The replace is:
0 Self explanatory
$1 Returns the single no. that was captured

Thanx alot for the help!
