I can't get the Script right now, but when i get it i'll put it here if possible. My computer won't work and none of the computers we have at home have ROBLOX nor Roblox Studio. And i can't download them since they are not mine.
If it only works in studio I assume you're testing with F5 (Play solo). Use F7 (Start Server) to test in studio it's more accurate. Since it's a fireball script I'm pretty sure it's a localscript so if Filtering Enabled is on turn it off (It's a property under Workspace, you can just uncheck the box). I can't help you more because you don't have a script :/
