Errors with a code fragment

[tertu]

So, the following code fragment is throwing errors (it's trying to call enabled, which is nil for some reason??) and I can't quire figure out why.

local enabled = CV_RegisterVar{
    name = "ssvc_enabled",
    PossibleValues = CV_YesNo,
    defaultvalue = "No"
}
 
local function shouldRun()
    return (enabled.value == 1) 
        and (gametype == GT_COOP) 
        and (not G_IsSpecialStage())
end

Could somebody help, please?

EDIT: For reference, I am calling this from a bunch of different hooks, the relevant ones when this was called being a HUD hook and a MobjThink hook.

EDIT2: The mistake was elsewhere in my code. Oops.

You wrote CV_RegisterVar{params} when you need to write CV_RegisterVar({params}).
