Sorting sections within large table

[Javid]

Hello my good friend, I hope you are well. I was a few days late due to a serious illness (pulmonary embolism) and I am sorry that I could not work during these few days. I want to summarize and do this as soon as possible. Of course, if I can count on your help.
The FILTER formula you used was very helpful and I was not able to use it properly before and thank you very much
I put the result of my efforts on the web for you. A file that contains 3 similar main tables and 3 summaries for them as well as 1 table for ordering goods. I still have a problem with this table, which I will explain to you about my requests. If possible, I would like to:
1- I want to mount this table on the summary of each of the main tables. (This means that we will have 3 order forms with their data tables.)
I am happy to see the image of each product in the order registration process of each product.
2- The information of these tables must be recorded and stored forever after entering the information and no mistakes will be deleted.
3- Possibility of summarizing based on each of the sellers separately.
I have written some necessary explanations as comments in different places in the file.
Thank you for your attention and help, my good friend, and I will wait for your reply.
Good luck.
