Alright, so I'm trying to make a game (Again).

So far, I had no errors until I tried implement shops.

Error:

AsciiRPG:204: attempt to call boolean

I know that a boolean is true or false.

But it only happends if I press the shop key wich I defined as 'p' twice.

Why?
How do I fix it?

Thanks for help //Mackan90096 (The Duck)

Well

elseif p1 == p then
        if shop == false then
          shop = true
          shop()

you define shop to be true and then call it as a function... Hence attempt to call boolean...

Oh.. DERP!
Thanks ..

Tip for the future: whenever you get an `attempt to call` error check your variables on the line number, check where you're overriding it etc.
