Problem in Absorption Barrier notetag value formula.

Using the above mentioned, I tried setting the default Guard command to recover barrier equal to 10% of the character's max hp.
This is what I tried (along with some other variations of it):

<User Barrier: +(user.mhp * .1)>

How should I actually be writing it to get it to work?

Are you sure that style of notetag accepts Javascript? The example doesn't seem to indicate that. You may want to try the Lunatic mode notetag instead

Oh yeah, I was being dumb, thanks.
