Could I get some examples of selected & deslected connections?

[Jacob__mybb_import1]

It should be:

Code:

link(script.Parent.selected,
function()
cam.FollowObject = car
cam.ScaleFactor = 50
end)

or

Code:

function onSelected()
cam.FollowObject = car
cam.ScaleFactor = 50
end
link(script.Parent.selected, onSelected)

The second argument is a function, not just a piece of code.
