Visual Basic - Issue connecting forms and displaying input

Whats up everyone, so I am new to coding in general but have been working very hard to learn and have been scouring the web for answers but none that worked. I have a basic program I am writing for a project, where you order a candle. On a form (frm_Order) I have labels for input of name address etc... Then you hit proceed and it takes you to the next form. On that form it is a summary of the order both the customer information, and the contents of the cart (lst_cart) on the first form (frm_items). So I have two boxes summarizing the order. How do I write the module to make that work or is there an easier route? Also when it opens each proceeding form, how do I make the previous one close so that there arent 3 windows open? Thank you so much for any help you can provide in advance this has been a rather frustrating and time consuming learning process, look forward to hearing from, cause lord knows I need the help! lol
