tagFormat : booklet command

[Emmanuel]

I appreciate your help!
Unfortunately it doesn't work here.
I tried every possibility:
- Comment.displayFormat={$*infoFileURI^<a href="^">booklet</a>$comment} > in tagFormat only > rescan > error message
- Comment.displayFormat={$*infoFileURI^<a href="^">booklet</a>$comment} > tagFormat + index Tags > rescan > same
- item Tags refuses to add command line as it shows following msg: Invalid item tag name 'Comment.displayFormat={$*infoFileURI^booklet$comment}'; correct highlighted value and retry
