What does this lua error message mean?

[Funkgary]

I am kind of new at writing LUA but I got this error message:

01:43 [XenoScript] [Knight]Killer Caiman.lua: '(' expected near 'setWalkerEnabled'

Just wondering what it means I did wrong?

setWalkerEnabled is a function, as such it requires parentheses and an argument.


setWalkerEnabled(true)
setWalkerEnabled(false)
