Math random Problems, when I play the game, it doesn't work?

I have this math random script, that takes a model out of lighting at random, but when I play the game, it always ends up doing one model, instead of a mix of the ones that I have. Does anyone know what's wrong?

value = 0

wait (.05)

value = math.random(1,2)

if value == 1 then game.Lighting.Model1:clone().Parent = game.Workspace if value == 2 then game.Lighting.Model2:clone().Parent = game.Workspace end end

For example when I click play in studio, it might work, but when I actually play the game it ALWAYS does only one of them.

Its purely the seed used. There's an answer somewhere on the wiki that i can't find.
