warning: Invalid argument supplied for foreach() in

Hi everyone,

I've installed CCK slideshow, on Drupal 5.7 with CCK, nf_registration_mod and node profile. When I go to the register page I go this error:

warning: Invalid argument supplied for foreach() in /home/newmill/public_html/sites/all/modules/cck_slideshow/cck_slideshow.module on line 279.

This is line 279 php code:
foreach ($type['fields'] as $field_name => $field) {

Can someone help ?

Thanks
