My app has few tabs and a gallery in homescreen, on the selection of tabs I want to sort the data in the gallery on the basis of certain condition
1 clicking on the first tab will display the entire data from sharepointlist in the gallery
* when clicking on the fourth tab , I want to filter the data in my sharepoint list , But it is showing some error,

SUPD is my sharepoint list , by clicking on the fourth tab i need to show all the data which contains the " Rejected"
4,Filter(SUPD,Contains.value="Rejected"))
Could anyone help me to fix this
