Hi, I've just spent nearly two hours searching through the forums and experimenting with the Replace, Format Value; & Guess Value functions in order to solve a problem with sequential numbering, but all to no avail. Would someone be so kind and please let me know how to apply sequential numbering after a colon, wherever it may appear in a track title? For example, how can I apply sequential numbering after the colon if I highlight the following tracks... Brandenburg Concerto No 1. in F-major: Allegro Brandenburg Concerto No 1. in F-major: Adagio Brandenburg Concerto No 1. in F-major: Allegro In order to look like this... Brandenburg Concerto No 1. in F-major: 01. Allegro Brandenburg Concerto No 1. in F-major: 02. Adagio Brandenburg Concerto No 1. in F-major: 03. Allegro Note. I require a space before, and a full stop and space, after each number. Any assistance would be most appreciated. Regards, Richard ---

Why do you write this in the section "Bugs"? You have to do it seperate for each classic and so in your example have to mark these 3 files in the right order. Define an action group with subsequent 3 actions: Type: Guess Values Source Format: %title% Guessing pattern: %title\_temp1%:%title\_temp2% Type: Format Value Field: %title% Format String: %title\_temp1%: $num(%\_counter%,2).%title\_temp2% Type: Remove Fields Fields to remove: %title\_temp1%;%title\_temp2% Edit: Typo correction in second action. ---

Once you have a tagfield named TRACK, which contains the current tracknumber, you can replace the old string ': ' with a new string like this action can do it ... **Action "Format value" Field : TITLE Formatstring: $replace(%TITLE%,': ',': '$num(%TRACK%,2)'.

I've been using DetlevD's formula for applying sequential numbering in the example I described above, where track numbers match Classical work numbers, and have had 100% success. However, I would like to apply your formula now, where track numbers don't match Classical work numbers. Unfortunately, regardless of whether track numbers are in sync with Classical work numbers or not, I get stuck on the Format Value action due to a SYNTAX ERROR IN FORMATTING STRING message being returned. Are you able to clarify whether... %title%\_temp1%: $num(%\_counter%,2).%title\_temp2% is a valid string or not please? Thank you. ---
