Help with Button with A Drop Down List and previous and next function for a Dynamic Page

Try this one…

$w.onReady(function () {
    $w('#dropdown1').onChange(()=>{
        $w("#dataset1").onReady(() => {
 let currentIndex = $w('#dropdown1').selectedIndex
            $w('#dataset1').setCurrentItemIndex(currentIndex)
 let currentItem = $w('#dataset1').getCurrentItem()
            console.log(currentItem)
            console.log(currentItem.title)
 //  let URL = "" //<---- modify to Dynamic-URL
            wixLocation.to(["memberprofiledata-1/{Title}"]) 
        })
    })
})
