use exhost with page directive? 🔗 link

In my hobbit-alerts.cfg, I have a bunch of alert definitions that start

 
PAGE=Main/Subpage 

MAIL emailaddress

SCRIPT /smsplus.sh 

 
If I want to exclude a single host from alerting within the subpage,
what's the best way to do this?

 
I tried PAGE=Main/Subpage EXHOST=testhost, but I'm still getting alerts
on it...

 
Are the page and exhost directives not compatible?
