264736 php combine data

I have created a basic CMS using the instructions given at the following address: [login to view URL] I have created a form with the following fields and can post the data to the relevant table on the MySQL Database: Product_code, Make, Model, Serial_number, Bullet_points, Description, datasheet_address, datasheet_link_description, datasheet_image_address, instructions_address, instructions_link_description, instructions_image_address, google_analytics_code I need to combine these pieces of information, so that they can update one field in a separate table, with a matching 'Product_code', when submit is pressed. the bullet points will be shown with bullets the link image will appear next to the link description and the image and description will have the html tag from the relevant *_address the row will only be shown if a link description has been entered in the field, otherwise neither of the three components should be shown.
