Okay, so we will have a variable that will do this work. On Click on WIN 1 button add below formula -
Set(varButtonWIN, "WIN 1")
Similarly on click on WIN 2 button add below formula -
Set(varButtonWIN, "WIN 2") and for WIN 3 button add below formula-
Set(varButtonWIN, "WIN 3")
In the gallery on click of thumbs up icon we will check,
Switch(varButtonWIN, "WIN 1", Set(varWINText1, ThisItem.Title); Set(varWINText2, Blank()); Set(varWINText3, Blank()), "WIN 2", Set(varWINText1,Blank()); Set(varWINText2,ThisItem.Title); Set(varWINText3, Blank()),
"WIN 3", Set(varWINText1,Blank()); Set(varWINText2, Blank()); Set(varWINText3,ThisItem.Title) )
Set text value of 3 labels to varWINText1, varWINText2, varWINText3 respectively
