SetRunSpeed, SetWalkSpeed, and SetPlayerSpeed all not working :[

[wizardsbane]

Hello, I'm trying to begin work on a gamemode, but I can't get either of the aforementioned functions to work. I've been putting the functions in the init.lua file of my gamemode. I've tried putting them all in hooked functions, I've tried putting them all under the GM:PlayerSpawn function, I've tried putting GM:SetPlayerSpeed all on its own and nothing changes in the game. Even when I try using lua_run with the wiki code on GM:SetPlayerSpeed that works on other servers, it won't change either. What do I do? :[

Where do I add or fix what I need to for this to work?
