I can never overcome this error!

I’ve reached an error “attempt to call method ’ ’ (a nil value)”

I’ve been trying to find answers that i understand,

looking through my code and trying to find out whether I have made any small silly mistakes,

but i just cant find any solution

I have two pages currently, the main page works fine no problems, but the options page is kicking up the fuss

even though the code is basically exactly the same

Please someone help me!

What actually causes this error? so I can look out for it in future

Does anyone have any idea whats wrong with my program? (I’ve attached the .lua files)

Typo? … you named the function “initalise” (missing an i) 

Wow, I’m a fricking idiot

Thanks a lot man, I’m such a fool
