can't get toUpperCase to work

I'm trying to ask a question with different strings as the correct answer. I'm trying to avoid people getting it wrong because they didn't use uppercase lettering. var questionThree = prompt('Name a country in Scandinavia'); var questionThreeAnswer = questionThree.toUpperCase; alert( questionThreeAnswer ); The variable doesn't give me the answer in uppercase but instead says this "function toUpperCase() { [native code] }". What am i doing wrong?

Since "toUpperCase" is a function, the name must be followed by parentheses to invoke it even if no arguments are being passed in them.

var questionThreeAnswer = questionThree.toUpperCase();  // <- note the added ()'s
