# Geometry of flowers

It says error on line 21 move xy requires to numbers as arguments x is nan which is type ‘number’, not ‘number’

Nvm i beat it i just had to fix the drawSquare part

Nan means"Not a Number". It is a special value which that x cannot be used as a number.
In your case drawSquare expected 3 values (x,y,size) and you gave him a structure and a value
( (x,y), value).

If you have a structure such a pos, you can get the value in the structure with pos.x an pos.y:

``````whiteX = {"x": 44, "y": 36}
#drawSquare(44, 36, 10)
drawSquare(whiteX.x, whiteX.y, 10)
``````
