Very nice.

Two things in addition to the product kit issue and line 216 noted above:
1) without uc_attributes installed, the module just dies.
2) i am getting these errors:

* warning: Invalid argument supplied for foreach() in /home/lushlila/public_html/drupal-5.7/sites/all/modules/uc_stockedit/uc_stockedit.module on line 363.
* warning: Invalid argument supplied for foreach() in /home/lushlila/public_html/drupal-5.7/sites/all/modules/uc_stockedit/uc_stockedit.module on line 392.

note, i do not have product classes. i have no attributes or product kits either if they make a difference.

Thanks for the great software. Hopefully these can get resolved in next release.
