client first and last name in hook

[ags]

How can I show the clients first and last name in a support ticket hook. I got everything else working such as userid, message, and subject. But I can't get the first and last names to show. I tried $firstname and $lastname as a varible but it doesn't show.

I figured it out by using: https://forum.whmcs.com/showthread.php?10105-display-variables-outside-whmcs

I spoke to soon, it's working when the client answers the support ticket directly but not when they reply through email. If anyone can help out that would be awesome!
