Variable for 'days remaining' in notification?

Variable for 'days remaining' in notification?

We've inadvertently changed the default message on our AD Self Service Plus "password expiry notification" email, removing the variable that was in there for 'days remaining'.  We'd like to get it back.
 
Could you post back here with what the variable you use for this item is?
 
We want it to say "Your password will expire in xx days" where xx is the number of days left before expiry.  I've tried %days% just as a guess but that simply puts the username in there instead...not sure why. 
 
Thanks very much!
