Is it possible to use a MouseButton1Click function in a loop that creates text guis?

I don't know is the question properly reflects what I'm trying to do, but I'm not sure how to word it. I'm making several textbuttons and I want to be able to tell whenever one of them is pressed, but they all have the same name and I don't want to have to adjust my script to accommodate different names and I don't want to have to write functions for each name. My code:

for i,v in pairs(spweps) do
            box = primary:Clone()
            box.Parent = loadoutbg
            box.Visible = true
            box.Position = primary.Position + UDim2.new(0.0,0,0.11*i,0) - UDim2.new(0.0,0,0.11,0)
            box.Text = v
            box.Name = "gunselect"
            v.MouseButton1Click:connect(function() --line 80 in case you couldn't guess
                if game.Lighting:FindFirstChild(v) then
                    local gun = game.Lighting[v]
                    player.Primary.Value = gun
                else
                    print("Not in lighting")    
                end
            end)    
        end

Output: Players.Player1.PlayerGui.SpawnGui.Menu:80: attempt to index field 'MouseButton1Click' (a nil value) A piggyback question I have on this one is is it possible to have multiple guis that when clicked fire the same function? something like this:

gui1.mb1d or gui2.mb1d or gui3.mb1d:connect(function()
    --Stuff
end)

or

local numbers = {"1", "2", "3"}
for i,v in pairs(numbers) do
    gui..v.mb1d:connect(function()
        --Stuff
    end
end
