You can write your topic however you want, but you need to answer these questions:
What do you want to achieve? Keep it simple and clear!
I want to be able to just convert all those scripts so that its copied from another script, instead of having to manually fix all the game warnings and errors…because manually doing that is gonna take ages.
What is the issue? Include screenshots / videos if possible!
The best practice is to make a script that handle all the parts but, if you really want to paste the same script into each part just copy the good scrip, select all the parts and hold ctrl shift v. that will paste the script inside every part selected
