Here's my expert brown townysis:
Your issue lies on Line 0.
OnActivate -> Self -> VCE_ifVariable -> "<var:cl:lastmsg>" -> ">=" -> "Wand" -> "1 4"
The problem is your output event, VCE_ifVariable. See, that only works for user-defined variables, however, the client's last team message isn't defined by events. Therefore, the correct way to do this event would be:
OnActivate -> Self -> VCE_ifValue -> "<var:cl:lastmsg>" -> ">=" -> "Wand" -> "1 4"
VCE_ifValue is used for all the player, client, global, minigame, and vehicle variables that use vce's tagging system, so you have to use that whenever you check something like <var:pl:health>. Yes, Zeblote answered this question about 3 posts up, but I went into more detail with it so you understand why to use VCE_ifValue.
You're quite welcome!
