I have indexTags including .., #AudioData:Audio Data, #AudioFormat:Format,

And then tried tagFormat of #AudioFormat.indexFormat={$#audioformat$#audiodata}

But no joy. Should this be possible?
thanks again, sorry for hassle,
Karen.

The answer is in the following paragraph:-

The indexFormat option doesn't replace any existing tags in the item. For example, the option
WorkByTitle.indexFormat={$title$tonality$opusnumber$subtitle}
would add a WorkByTitle tag if it doesn't exist in this item. No tag would be added if the item already has a WorkByTitle tag. This limitation doesn't apply to the Artist tag.

Above extracted from the Index tag formatting section of the user guide.

Try adding an index entry, that is not an existing tag, and refer to it in an indexFormat entry.

Hi Alan,

yes, I am trying to work from the user guide, but I keep getting syntax errors. I have just tried what I think you are suggesting but still no luck. i.e. in the tagFormat I now have :
FormatDetails.indexFormat={$#audioformat$#audiodata}

So where I am going wrong?
thanks, Karen.
