@v-yamao-msft Thanks, we have temporarily changed the column to a multi-line text column. But we really need to do a filter based on several boxes, one is a what's been selected in the drop-down boxes. All three are drop-down boxes but the last two are from Choice Columns in SharePoint.
Here are some more details.
Books = collection from SharePointListName
Books Title Drop down:
SortByColumns(Distinct(Books, BookTitles),"Result")
Old/New Drow down:
LookUp(Books,BookTitles=BookTitles_ComboBox.Selected.Result,Old_New)
Genre
LookUp(Books,BookTitles=BookTitles_ComboBox.Selected.Result,Genre)

Book Titles - Many different Book Titles
Old Titles/New Titles - Choice column between Old Titles or New Titles
Genre - Choice column of Development, Fiction, Non-Fiction
The Gallery displays based on what is selected in the filter.
Gallery Filter:
SortByColumns(
Filter(
SharePointListName,
If(
BookTitles_Var,
BookTitles = BookTitles_ComboBox.Selected.Result,
true
) && If(
OldNew_Var && Genre_Var,
First(Old_New_ComboBox.SelectedItems) in Old_New && First(Genre_ComboBox2.SelectedItems) in Genre_3,
true
)
),
"Priority_Order",
Ascending
)
The Gallery then displays based on the filter:
