Hi @prizemac
The button is only doing one thing at the moment and that is to put the Fahrenheit value into the h2. You need to make it so that it can detect whether it’s currently displaying Celsius or Fahrenheit and then change to the other value, you could use a class to identify the current unit.
Perhaps something like this if you get stuck:
$("#tempC").addClass("celsius");
/*toggle button*/
$("button").click(function() {
$("#tempC").empty();
if ($("#tempC").hasClass("celsius")) {
$("#tempF").html(tempFah + "°f");
$("button").html("C/F");
$("#tempC").removeClass("celsius").addClass("farenheit");
} else {
$("#tempF").html(tempCel + "°c");
$("button").html("F/C");
$("#tempC").removeClass("farenheit").addClass("celsius");
}
});
