Business Rule Exception : How to Skip typing values in web page field if data not found and continue with further execution?

I’m trying to enter values into the Web Page

The values are fetch from the Excel Sheet.

I have to apply a business rule exception. i.e: If the First Name Value is found empty in the excel sheet, Robot should not enter the remaining values. It should just skip that whole row.
So basically, Robot should enter values of 3 rows. and skip rest of the 2 rows as they don’t have First Name.
