what if the last name in iteration comes first than description than your variable won't have value to copy in last name?
Please explain this scenario

[@salesforcein5minutes]

If that happens then in that case lets say you are typing 'Test' in description so at first interation no value will be assigned to last name as last name is executed first and after that description has the value
Then in next interation Description is going to hold 'Te' but your last name will get populated with ' T ' as previous value of your description was 'T' and maybe one word might be missed and last name will be populated with 'Tes' instead of 'Test' as it might miss last iteration
