Why Sword Work For Studio But Not Game?

Why does this work for Studio but now the game?

Local Scripts no longer have the LoadString functionality as of;

4 September 2014

Client-side loadstring() no longer works; LocalScripts with LinkedSource property set also no longer work.

This is stated in the Roblox Wiki Changelog

The LoadString function has been removed from LocalScripts, due to exploitation of admin commands local scripts that previously allowed loadstring to work. Due to the exploitation, Roblox administrators heightened the security of games, by setting to false by default LoadStringEnabled property located in ServerScriptService, and disabling of LoadString in LocalScripts.

What you can try, to fix the admin command is by copying and pasting the code for the sword script into another local script, and placing that script into the sword as it is created.

In the future, please recognize this is ScriptingHelpers, we do not find errors for you, we do not make scripts for you, we help debug and solve issues for you. We also do not accept copy and pasted code as well. Thank you.
