SharePoint Lookup Pack bundle of three products that enhance and compliment the default SharePoint lookup column function. Quickly cross-reference data from a list or site then apply a combination of filters to reduce the options presented in menus to eliminate error from incompatible values. Cross-site Lookup refers to information from another site, while Cascaded Lookup establishes more relationships with lists then trims down information as choices in lists are made. Lookup Tracker summarizes information related to an item in a list.
