So i take a look again it isn't in starter gear but it's in back pack but it still says Fireball is not a valid member of back pack and here's what i do so far:
wait(0)
for i, v in pairs(game.Teams["Civilian"]:GetPlayers()) do
v.Backpack:Fireball():Destroy()
end

try :WaitForChild()
i dont know where to put WaitForChild()
Can you explain with more detail exactly what you're trying to accomplish with this script? Also post the script that you have so far
ok
i think the problem is the proper usage of localscript and normal script
if you made something with local script, it wont replicate into the server. which means if you tried to find that thing you made with a localscript you will certainly not find it
Should it not be v.Backpack.Fireball:Destroy()? Instead of v.Backpack:Fireball():Destroy().
