Oh, I see what you did. You copied from the documentation. Generally in documentation it's standard to put the type of variable that a function returns after a colon. All you need is the part before :number. That part just tells you that that method returns a number.

So i dont need to put in ":number" because that is just telling me what type of variable its going to output?

I did that and now it says

/usedspace:1: attempt to call a nil value (global 'spaceUsed')

stack traceback:

             /usedspace:1: in main chunk

              (...tailcalls...)

Hey all, i'm a huge newbie at this and all of my lua programming  knowledge is from computercraft, and very little knowledge at that. I am messing around with OC and am trying to make a program that displays the used space of the hard drive(s) that the computer(server in this case) is connected to for learning purposes, what i typed was.

space = spaceUsed():number

print ("Your used space in bytes is:", space)

and it gives me

/usedspace:2: function argument expected near 'print'

when i try to run it. Im not sure if what im doing wrong, or even if that is valid lua.
