Either you use `$upper` with the extension comparison in UPPERCASE

```auto
$if($eql('TTA',$upper(%_EXTENSION%)),$repl(%TITLE%,' TTA',' '),)

```

or you use `$lower` with the extension comparison in lowercase

```auto
$if($eql('tta',$lower(%_EXTENSION%)),$repl(%TITLE%,' TTA',' '),)

```

Do you want to replace the tta string in all variations like `tta`, `tTa`, `tTA`, `TTa`, `ttA`, `TTA`?  
Or what case should be ignored?

**Later added warning:**

> **Please don't use this abbreviated syntax!**
>
> As found in this [bug report](https://community.mp3tag.de/t/similar-actions-get-mixed-up/56456), the abbrevation of `$repl` instead of using `$replace` can result in unwanted changes. Always use `$replace` as stated in the [help.](https://docs.mp3tag.de/scripting/#string-functions)
