Lua value not changing?

I use very simple Lua scripting in an online game called ROBLOX. My problem is that values in my scripts aren't changing! Example:

num = 0
while true do
    num = num + 1
    print(num)
    wait(1)
end

That should count up starting on 0, but the number won't change. Could this be from the ROBLOX website? I can't figure out what else it might be.

Try this:

local num = 0
while true do
    num = num + 1
    print(num)
    print(type(num))
    wait(1)
end

There is no error in your code. If you are using ROBLOX, then I'm not sure how you're running it wrong as it is a fairly simple interface. I'll try it in ROBLOX and see if it errors for me.

To the people who were wondering about wait(): it's a ROBLOX-specific global function, that pauses the current task the amount of seconds in the parentheses.

There is nothing wrong with the code. You must be running it wrong. Also, wait is a function defined in the Roblox API. It is legit.

I just put your code in the Lua demo and it works fine if you remove the wait() function call. I'm assuming you defined this function somewhere?

What happens with 

local num = 0 
while true do 
    num = num + 1 
    print(num) 
    wait(1) 
end

?

Maybe some other part of the system is changing the global num.
