I have a PowerApp based on SharePoint list. I am storing RMS_Contractor (choice field in list) and using it in the PowerApp.
The Browse Gallery Title1 is Text = ThisItem.RMS_Contractor.Value
Search Items (BrowseGallery1.TextSearchBox1:
SortByColumns(Filter([@RMS_Contractor_Safety_Incident_Report], StartsWith(Title, TextSearchBox1.Text)), "Title", If(SortDescending1, Descending, Ascending))
I am sure this is not working because I am not storing the RMS_Contractor (type=Choice) in the Title (Type=text) field of the SharePoint list.
