Hi Edwin,

Random randomGenerator = new Random (); // changed randomgenerator to randomGenerator (upper G)
int randomNumber = randomGenerator.nextInt();

And delete the space between Random and () to:

Random randomGenerator = new Random();

This one is giving me a hard time too :( Create a String variable named intAsString. Convert the randomNumber integer to a String value and store it in the intAsString variable. Hint: Add them together like in the video!

Ok lets see:

String intAsString = String.valueOf(randomNumber);

Use the method valueOf from the String class to convert randomNumber (integer) into a String

edit: Sorry for incorrect suggestion.
