To put a value into a variable, you use the assignment operator ("="). This goes between the variable name and the value you want to give it (instead of enclosing the value in parentheses).

Parentheses are used to pass arguments to functions,.

Also, you wrote "toUppercase" (with a little "c") instead of "toUpperCase" (capital "C").

Chase the text's colors on your app.js and you will find out 2 details missing. As a beginner as well I can say that the SyntaxError is the most often mistake we make. Good tip is use the Develop Tools (Ctrl+Shift+I on chrome) to open the JavaScript on your browser, it will help you to find out why your code isnt running properly.
