what is the symble beetween the x and the 8 and the y and the 8 in this function:

function draw_player()

 spr(p.sprite,p.x?8,p.y?8)

end

That's an asterisk! Shift-8. In coding, * is used for multiplication.

so when i run it it says "ERR :45: attempt  to index global 'p' 

(a nil value)   

ps i am on liko 12 a pico clone so this could be the problem
