Missing argument 2 for slider_textfield_help()

Thanks for making this module. The idea of using sldiers for numerical values makes a lot of sense. I'm glad this is now readily available in Drupal.

Initially installation of the 5.x version of this module produces this error.

"Missing argument 2 for slider_textfield_help() in /var/www/library/sites/all/modules/slider_textfield/slider_textfield.module on line 13."

However, the above error is fixed by changing line 13:

function slider_textfield_help($path, $arg) {

to

function slider_textfield_help($path, $arg=array()) {
