I want to know how to make a zoom script where you can only zoom out a certain length?

So I was looking everywhere for tutorials, even trying to make a minimum zoom scrip myself but it does not work.

I want to know how to make it so you can only zoom out a cetain length. Like shortening the zoom length so players cant zoom out that far.

If you can help, that would be great. If you cant, its alright

Try this link: link

Example:

player.CameraMinZoomDistance = 75
