Functions and variables inside a package not working as expected

[rajasegar]

(css-lite:make-css-func my-border-radius (radius) (list :border-radius radius))

(defun my-css ()
  (css-lite:css
    (("#foo") ((my-border-radius "5px"))))

should return

`

foo {

border-radius: 5px; } `

instead it returns

`

foo {

my-border-radius: 5px; } `
