error message -can't append all the records in the append query

Please help me as well. I am working with access database I have very limited experience with Access. Microsoft Access can't append all the records in the append Query microsoft access set 0 field to null set to convertion failure and didn't add 2841 records to the table due key violations 0 record due to key lock violation.
Would this also indicate duplicate records in the table....?
