barcode scanner not picking date up

hi
i have been racking my brains for 2 days now and have not come up with a solution can any one help please,i scan in barcode in frmissued and save ,writes to sheet3,frmret runs ,scan in barcode and all boxes are filled apart from issue date , and 4 bowes at the bottom which is looking up sheet3,
have 3 long codes in combobox that seem to work,have tried different length barcodes still no good,could it be wrong sort of barcode have used 39,coding not good,tried formatting boxes or something just mind boggling easy,this is the last piece to get working before i can use inventory,please someone out there must be brainy enough to figure this out
cheers colin
forgot to say frmret must be picking up the issue date because it transfers it to sheet3 but does not show on userform weird
