I have a script that when you shoot a target it actives another script that gives you the point but how do you make the first script activate another script..?
You can just use the "Disabled" value of the script. While disabled, the script will not run, and when you enable it then it will run from the start.
A script like:
local ScriptToActivate = workspace.Script ScriptToActivate.Disabled = false --It will run
Although the "ScriptToActivate" would have to be disabled in the first place, which can be done via the properties window.
