Evening,

Run into a small snag (due to miss typing the code)

For a multiple Genre you use the format Genre//genre2//genre3 and it works great however, for late night keyboarding, I used the \ instead

I tried to run a replace action  
Field : Genre  
Original: \  
Replace with //

but that doesn't work so more scripting is probably needed. The Genre I have are different for a lot of my files so the only thing is a replace action script that replaces \ with // or another scripting function.

Any Help for this would be appreciated

It could still be that you have a multi-value field for Genre right now.  
Check this in the extended tags dialogue. If you see more than one GENRE field, it's multi-value.  
To handle these fields, it would be easiest to merge them.  
There is an action for that: [Merge Duplicate Fields – Mp3tag Documentation](https://docs.mp3tag.de/actions/merge-duplicate-fields)

If you enter `//` as separator, you should get the preferred format straight away.

No, you should use `\\` for multiples.

...and since it seems that you want to split, use "Split field by separator".
