On the lookup tab you can manually lookup LRN information for a specific number.
There are two types of lookup that can be performed, simple and extended.
Simple lookup will only return the LRN of the number.
Extended lookup will return the LRN of the number plus additional lerg data. You preform an extended lookup by checking the "Extended Lookup" check box.
The reports sub tab is where you can view how many look ups you have preformed over a certian time period and how much money you have spent on look ups over that same period.
