Two ways to get to a filtered data table

[Techgallagher]

Hi, I have two galleries, one is a more detailed gallery and the other is more general; however, I want to be able to navigate to a different screen that has a data table on it that will populate based on whether I pick from the first gallery or the second. As of now, it only is working on the first gallery selection, if I choose an item from the second gallery selection it will still just bring up whatever was last selected on the first gallery. 

Gallery 1:

Gallery 2: 

This is the current formula I have for the items property of the data table:
SortByColumns(Search(Filter('[dbo].[970_item_format_item_mast]',
(part_name = 'Part Selection Gallery'.Selected.PartName || part_name = 'Image Gallery'.Selected.'Part Name')
