I have been trying to write a WS for [AudiobookCovers.com](http://AudiobookCovers.com) but I cannot even get it to to output the debug text.
Here is what I have so far
```typescript
[Name]=AudiobookCovers.com
[BasedOn]=https://audiobookcovers.com
[IndexUrl]=https://audiobookcovers.com/search?q=%s
[AlbumUrl]=https://audiobookcovers.com
[WordSeparator]=+
[IndexFormat]=%_coverurl%|%_url%
[SearchBy]=Enter Album Name||%album%||%s
[Encoding]=url-utf-8
[UserAgent]=1
[ParserScriptIndex]=...
DebugWriteInput "E:\Test\test.html"
Debug "on" "E:\Test\test.txt"
# URL
findline "a class=\"max"
findinline "href=\""
sayuntil "\">"
say "|"
# CoverURL
findline "audiobook cover image"
findinline "src=\"" 1 1
sayuntil "\">"
outputto "coverurl"
[ParserScriptAlbum]=...
```
I get the input pre-filled pop-up window
which doesn’t get any hits (kind of expected as this is 1st attempt)
Only “Retry“ & “Cancel“, no “OK“
And that’s it. I doesn’t write either the DebugWriteOuput or Debug.
I have tried multiple locations (as I know Mp3Tag requires writinh priveleges) to no avail.
This seems like it should be pretty straightdoward, I’m sure it’s user error on my part. What a, I doing wronng? Can anyone help?

Have you tried to use `Debug "on" "E:\Test\test.txt"` line before the `DebugWriteInput "E:\Test\test.html"` line?
I'm not sure if the output format `.html` is supported. Personally, I use `.txt`
From the documentation about "[debugging](https://docs.mp3tag.de/tag-sources/development/#debugging)" a Websource Script:
> To check what the parser is doing, you can add a `Debug "on" "debug.out"` **command to the top of your script**. This will give you an output file which will show you step by step what the parser is doing and why you end up with a given output.
>
> You can use `DebugWriteInput "debug-input.out"` to see what data you are actually parsing and before you build your script step by step.
BTW: I assume the `E:\Test` path is accessible and writable for Mp3tag?

Can confirm, I changed to save the debug files in the .src’s folder and it saves:
```auto
debugwriteinput "C:\Users\Owner\AppData\Local\Packages\35795FlorianHeidenreich.Mp3tag_rf0p6xgxmspcc\LocalCache\Roaming\Mp3tag\data\sources\IndexInput.txt"
debug "on" "C:\Users\Owner\AppData\Local\Packages\35795FlorianHeidenreich.Mp3tag_rf0p6xgxmspcc\LocalCache\Roaming\Mp3tag\data\sources\Index.txt"
```
It CAN save `.html` but doesn’t show up exactly the same as the website, though I assume it’s for use with an editor to rake through the code easier.

I just changed it to
```typescript
Debug "on" "E:\Test\test.txt"
DebugWriteInput "E:\Test\test_out.txt"
```
it made no difference.
And yes, E:\Test is accessible and writable for Mp3tag.
I previously tried just “Text.txt” which should just use the sources folder of Mp3tag, shouldn’t it?
I only added DebugWriteInput because it wasn’t outputting “Text.txt”
Thanks for quick reply

I am using portable version. Would this make a difference?
I have tried multiple locations and nothing.

Please try it with the path that you get with `%temp%` in your Windows Explorer.
Something like `C:\Users\MyUserName\AppData\Local\Temp` and
```auto
Debug "on" "C:\Users\MyUserName\AppData\Local\Temp\audiobook_debug.txt"
DebugWriteInput "C:\Users\MyUserName\AppData\Local\Temp\audiobook_debugWriteInput.txt"
```
I have just copy & pasted your code and obtained both files.

I have just tried
```typescript
Debug "on" "C:\Users\azaze\AppData\Local\Temp\test.txt"
DebugWriteInput "C:\Users\azaze\AppData\Local\Temp\test_out.txt"
```
and
```typescript
Debug "on" "C:\Users\azaze\AppData\Local\Temp\test.txt"
DebugWriteInput "E:\Applications\MP3TagPortable - Audiobooks\data\sources\test_out.txt"
```
but neither produce any new files
Changed the install path from `E:\Applications\MP3TagPortable - Audiobooks\` to `E:\Applications\MP3TagPortable - Audiobooks\`
and ran as admin
Still no files.

Can you check if you find a scripterror.log in your data folder? Maybe there is an error in the script and it's not even interpreted.

Can you try
```plaintext
Debug "on" "E:\\Test\\test.txt"
DebugWriteInput "E:\\Test\\test_out.txt"
```
