Sudden White Screen? - Interpolating Camera

This script is to move through cameras and locate the focus and CoordinateFrame inside models. The movement is fine and is actually exactly what I'm looking for, but once the Camera goes into position, the screen turns white. Any insight on this will help, thanks.

Button.MouseButton1Click:connect(function()
    Viewing.Value = Viewing.Value+1
    local Current = Towers:WaitForChild("Tower"..Viewing.Value)
    local Pos = Current:WaitForChild("View1")
    Cam:Interpolate(CFrame.new(Pos.Position),(CFrame.new(Pos.Position)),5)
end)
