We have created a DB with, amongst others, tables containing Country and Region data.. We have created the following function to filter the region Dataset based upon the CountryName selected from the Country DropDown... This does not seem to work at all... any help would be appreciated Thanks... [code] export function CountryDd_change(event, $w) { //Add your code for this event here: let myCountry = $w("#CountryDd").value; console.log(myCountry); $w("#RegionsDataset").setFilter(wixData.filter().contains("CountryName", myCountry)); [/code]
