    The error message is :
    HTML Code:
    Exception: Index: 5, Size: 5
    and when i check out my data base it will show that it inserted the attributes more 5 times in the data base not just one and couldn't continue to insert it more the i get the error message

    I don't know why i got this error, and i don't know why insert the attributes more that once!!!

    my excel file
    HTML Code:
    CD_ID	Albumtitel	  Interpret   created Track   Titel
    4711	Not That Kind	Anastacia	1999	1	Not That Kind
    4710	Not That Kind	Anastacia	1999	2	I’m Outta Love
    4712	Not That Kind	Anastacia	1999	3	Cowboys & Kisses
    4722	Wish You Her    Pink Floyd	1964	1	Shine On You Crazy Diamond
    4713	Freak of Nature	Anastacia	1999	1	Paid my Dues
    ps: the first row will not be inserted in the database so you can ignore it
