How do I make this script say "Hello Robloxians"?

I was learning how to script and then found a script where they say Hello Bob. Well, I then changed it to Hello Robloxians for each person coming to my game. This is the script:

function sayHello(name)
    print("Hello, " .. name .. "!")
end
 
sayHello("Robloxian")

function SayHello(Name)
print(Name..'!')
end

SayHello("Hello Narblet") OUTCOME --> Hello Narblet!

SayHello("Hello FUDGEWAD") OUTCOME --> Hello FUDGEWAD!
