Highlighting Rule for No Track Leveling

[phred]

I want to use a highlighting rule to show tracks that do not have volume leveling. I created this custom tag

Code

$IsNull(<Track Gain>,None,<Track Gain>)

but I'm getting an error "can't be parsed @ ">,None,<Track Gain>)"

Suggestions welcome.

Thanks.

Have tried your custom tag, and obtained the same result as you. Even indicates the same amount of tracks that are in the database. 
Sorry do not have a solution right now.

I'm not sure if you are using that formula as a virtual tag or as a rule?
One approach that should work:
Create a virtual tag: $IsNull(<Track Gain>,,<Track Gain>)
And then as a rule use that 'when that virtual tag has no value'...

I have no problem entering your formula into a virtual tag. Highlighting rule with the field also works fine.

I was creating a virtual tag, which I was then referencing in the rule.
Yours works. The difference being I was using 'none' and you're using a double-comma.
Thanks.
