To add a new mapping: 
                  		  
                   
                     			 
                     - Scroll down to the bottom of the page. 
                        			 
                     
- In the blank row at the bottom of the page, select values for each column. 
                        			 
                     
Note: Each time you click a field in the blank bottom row, a new blank row appears underneath to enable you to add another new mapping.
