How to assign multiple rows under same label to the data base (WFA VB2010)?

see i created a restaurant bill in windows form application 2010 . so first i created a data base with column names item_NO,Item_Name,Qty,Price,Total, Grand Total. i took a form and dragged that database as details view and i arranged the labels in columns and their respective text boxes under them .i want 4 rows of text boxes under same labels so i selected all first row text boxes by holding Ctrl key i made copy of them downwards. but when i debugged and inserted the values only first row values are assigning to database but remaining 4 rows are not assigning to data base. so i selected every text box individually in properties i bind every text box with respective data source columns names. but first row and second row values are binding to same database it arising a error . so what i need to do now either i need to modify my database or form give me a suggestion

see this image for clearly understanding all other remaining buttons like save,print preview ,print are working correctlyhttp://www.vbforums.com/
