Ok, before i start to reconstruct your project to make an example for you, please take a look at this example here. It is very similar to your needs.
In the example you will see the same given situation like yours.
You have a dynamic page (Courses) connected to the Courses-database, and on the other side you have the instructors.
The question was: “How to set a quote to the right instructor”.
Almost the same situation, like yours. Take a look here…

You will enter the “Overview-Page” which will show you the situation.
When you klick on the blue button, you will redirected to the dynamic page (courses) ----> like your “Lighting-page”.
Just take a look, i am sure it is absolutely the same process, as you need it.
And you do not need any —> Wix-Storage-Sessions to bring data to next page, this is not necessary.
Take a loo, and tell me if you could modify this example for your needs?
