+# Ask loosing this
+
+The call to `askPassword()` in the code below should check the password and then call `user.loginOk/loginFail` depending on the answer.
+
+But it leads to an error. Why?
+
+Fix the highlighted line for everything to start working right (other lines are not to be changed).
+
+```js run
+function askPassword(ok, fail) {
+  let password = prompt("Password?", '');
+  if (password == "rockstar") ok();
+  else fail();
+}
+
+let user = {
+  name: 'John',
+
+  loginOk() {
+    alert(`${this.name} logged in`);
+  },
+
+  loginFail() {
+    alert(`${this.name} failed to log in`);
+  },
+
+};
+
+*!*
+askPassword(user.loginOk, user.loginFail);
+*/!*
+```
