Hi Aqqi

var id = "23188xtr";
var lastName = "Smith";

var userName = id.toUpperCase(); //This makes var id uppercase.
userName += '#' + lastName.toUpperCase(); // we then add the '#' and lastName in uppercase

chris jardine how are you

First, you use the toUpperCase() method on the id and the lastName (you could do it on stage 2) variable. Then, you concatenate the id with a pound or hash symbol - # and lastName.

var id = "23188xtr";
var lastName = "Smith";

var userName = id.toUpperCase() + "#" + lastName.toUpperCase();
