Warning when added column to ecart object and buy now button
I have needed to add an extra column to e cart object for a productID (which is separate from itemID) after doing so and have bound the productID to the recordset for the buy now button. I get this error below and the page no longer redirect to cart.php. This is the warning below. I have checked to make sure there is not white space in the code which which is common I understand for "cannot modify header information".
Notice: Undefined index: Product in /Volumes/My Book/Cura Romana/Dreamweaver/CuraRomana Large official/curaromana/uk/IC24.php on line 68
Warning: Cannot modify header information - headers already sent by (output started at /Volumes/My Book/Cura Romana/Dreamweaver/CuraRomana Large official/curaromana/uk/IC24.php:68) in /Volumes/My Book/Cura Romana/Dreamweaver/CuraRomana Large official/curaromana/uk/IC24.php on line 91
I have uploaded the product pages as well as the ecart object page. The error come on the IC24.php page.
Many Thanks as always for your help
