Hey JC,

Say your fields are .station, .barge and .chocolate. You can use the following code to check if at least one of them is not empty. This will “short-circuit” if any one of those fields actually have a value, and will show your label.

export function repeater1_itemReady($item, itemData, index) {
$w("#repeater1").onItemReady( ($w, itemData, index) => {
 if( itemData.station || itemData.barge || itemData.chocolate ) {
        $w("#btnShowHide").show();
 }
 else { 
        $w("#btnShowHide").hide();
 }
});
}
