var ('x y') plot3d(x^2 y^2,(x,-2,2),(y-3,3))

I try this in Sage 5.11 Notebook:

`var (x' y') plot3d(x^2 `~~y^2,(x,-2,2),(y-3,3)) ~~y^2,(x,-2,2),(y-3,3))

But I got syntax error. I typed the figures correctly, but I don't know how to solve the syntax error.~~ ~~

var ('x y') plot3d(x^2 y^2,(x,-2,2),(y-3,3))
