I am trying to build an on leave field that can do the following. In a current form I have a field called SSN, upon leaving the field I would like a search to look at an xls spreadsheet for a field also called SSN and find the equal value "match" and then proceed to delete the row. Prior to deleting the row a dialog prompt should display first name, last name, ssn, and ask to confirm delete.

The field name on the XLS is on a column also called SSN.

Can anyone show me a sample on how to code this?
I am trying to learn how to interact with XLS.

Thanks
