I was wondering how you would do this,

15goodsong -\> 15. Good Song or 15. goodsong

the goal is to get the . after the # so if I have,

4 The Best Song Ever -\> 4. The Best Song Ever

This is for the Filename field (edit)

Thanks!

Create an action of the type "Replace with regular expression" for the field.  
Search string: ^(\d+)  
Replace string: $1.\_  
(where the \_ is a blank - of )  
If we are talking about the filename, you should use the function Convert\>Tag-Filename

Also, it could be necessary to remove double-blanks afterwards.

What do you mean by "tracktitle", ...  
does it be the tagfield TITLE, ...  
or does it be the pseudo tagfield \_FILENAME?  
Why don't you create the target string fresh from the TRACK number and TITLE string?

**TITLE \<== $regexp(%TITLE%,'^(\d\*)\s\*(.\*)$','$1. $2')**
