	fram.BackgroundTransparency = 1
end)

You could just use TweenService.

local FRAME = script.Parent.Parent.Parent.Parent.blockify.framblack1
script.Parent.MouseButton1Click:Connect(function() -- parent cannot be used; use Parent instead
     local tween = game:GetService("TweenService"):Create(FRAME, TweenInfo.new(1, Enum.EasingStyle.Linear), {BackgroundTransparency = 0})
     tween:Play() -- play the tween
     tween.Completed:Wait() -- wait for the tween to be completed, screen is black now
end)
