How to make drop down or checkbox change data in dataset

I don’t want to really filter any data… Let me see if I can explain better:

This is a portal for food & beverage orders to supply a restaurant to be more specific

I have one page that allows users to upload an order with multiple text boxes ( Order, Quantity, Notes, Order Date)

Once those are uploaded it goes to my “Order Review” page that has a list with all the orders in a table. There is a column for all mentioned above, as well as a “Completed” column.

I have the order column linked to a dynamic page that will bring up that specific order on a new page for “review”.

Once reviewed I want to have a checkbox/drop down that would signify that the order has been placed/completed. Once that action has been done I want the table on my “Order Review” page to update the column of that specific order to say “Completed” or have a check mark.

My problem:

If one order is submitted and reviewed at a time it seems to work and update just fine. However I have many different orders being placed daily by multiple people, so that would never be the case.

Right now if I upload 5 orders and click the one on the bottom of the table, select complete, it only updates the one on the top of my table. They are not working individually.

Ive uploaded some images to hopefully give a better idea. You will see only one record is selected as complete
