Help with my Price Referencing Spread Sheet

Hi Guys,

Okay, I am new to making complex (well complex to me, spreadsheets) I have only ever made simple ones before. I have made a spreadsheet for checking the invoices that I receive from the wholesalers (please see attached). I copied a guy on youtube to make this spreadsheet so I am a bit of a novice.

Basically, I have built a search engine and when I tick one my my tick boxes it appears in a information table to the right of my search engine. I want to know if it is possible that if I tick one of my tick boxes I want it to stay in the information box why I search for something else and then when I tick the second tick box that will also appear in the information table and stay there why I search for other items and when I untick them I want the information to disappear from the information table. This is so that I can basically rebuild the invoice that has been sent to me input the amount of items I have and then the total amount invoiced to me will be in displayed at the bottom in a total box.

I have attached the spreadsheet I am talking about.

Thank you in advance for any help, please remember I am very new at this.

Kind Regards,

David
