x = nil (not declared)
y = nil (not declared)
x and y have to be number values.

Edit:
Afterwards, you have to declare obstacle.

because x and y are declared in the function:
breath(id,x,y)
(this is possible because the movetile hook provides these coordinates)

variables which are not declared have no value (nil). they do NOT have a random value. you must assign a random value using math.random(min,max) if you want to have a random value.
