OnUpdate Issue

[Xabora]

EDIT: Resolved, thanks!

Are you passing that function to a frame's SetScript method?

local f=CreateFrame("frame")
local myOnUpdate = function(self, elapsed)
    self.t = self.t and self.t - elapsed or 1
    if self.t < 0 then
        self.t = 1
        print("hi")
    end
end
f:SetScript("OnUpdate", myOnUpdate)
