display content of cell based on selection of previous cell

[oscarviews]

Hello help please,

I have a table of narratives that I would like to be displayed inside the app.   Colum A name is called "name of narrative"  Colum B is called "narrative"

So in the app I have a entry that reference colum A , so I select one of those, but I would like Column B to be displayed below it.  

I will have a few "narrative names" maybe 10 or so and they all will have its own narrative next to it.

any help is appreciated.
