Hello, ́ I've searched, read here and tried around so much, but I need help. I want to copy a certain number from FILENAME (or TITLE) to TRACK, but I just can't get it... FILENAME(s): I'm a Podcast #123 (01.01.2001) - Artist I'm a Podcast #123 \_ sometimes with details (01.01.2001) - Artist TITLE(s): I'm a Podcast #123 (01.01.2001) - Artist I'm a Podcast #123 / sometimes with details (01.01.2001) - Artist Now I want to copy the number of the episode (#123, without #) to TRACK. If the hashtag is a bigger problem, I could remove it first and put it back in after. I hope someone can help me with my problem. Thank you and greetz Schoni ---

Try Convert\>Tag-Tag for TRACK Format string: `$regexp(%title%,'.*#(\d+) \(.*',$1)` Check the preview whether it works ---

Hi ohrenkino & thanks you. Unfortunately, the entire %title% is copied to TRACK. ☹ Greetz ---

That means that the applied pattern does not match the source. So please show a real title. In regular expressions every character matters. ---

Hello again, that's exactly why I chose the example title like the original, BUT: I have two spaces between the number and the date, but the forum only shows one after sending. Now, when I adjust the title to only one space, it works. The info will probably help you more than just posting it again with one space, hehe. Die Info Greetz ---

Screenshots sometimes work miracles. Here is what I get with the example string and a slight modification: `$regexp('I''m a Podcast #123 (01.01.2001) - Artist','.*#(\d+)\s*\(.*',$1)` 123 ![grafik](https://community.mp3tag.de/uploads/default/original/2X/2/29fece9e77000d9083c489db27133854983a52b0.png) ---

ich red eben mal deutsch 😃 das ist aber (wie es scheint) auch nur mit einem leerzeichen zwischen #123 und (01.01.2001) bei dir. wenn ich ein leerzeichen lösche, ging es mit %title%, genauso wie es nun geht, wenn ich dort nicht 2 leerzeichen hätte. VG ---

> [@Schoni](#): > > wenn ich dort nicht 2 leerzeichen hätte. I don't think that the number of space characters is the problem: ![grafik](https://community.mp3tag.de/uploads/default/original/2X/5/5802bc4a1d0ce662fe285f2c078eb0df922590d9.png) A screenshot of the real data would help a lot. ---
