Every time you click, that function is looping through the whole options table, from ONE to FOUR, calling SetText() and set() for each one. No matter how many times you click, you will always see FOUR, while the other three attempted to show within the frame you clicked.

I'm going to assume your default value is also in this frame since options is there.

function(self)
    local valueset
    if not self.firstload then
        self.firstload=true
        valueset=self.value
        for k,v in ipairs(self.options) do
            if v=self.value then
                self.lastindex=k
            end
        end
    else
        valueset=self.options[#self.options==self.lastindex and 1 or self.lastindex+1]
    end
    self.valueText:SetText(valueset)
    self:set(valueset)
end
