AngularJS split()

Hello all, i am a little stuck on an AngularJS function Inside my controller i have:

$scope.numWords = function(str) { var wordCount = str.split(",").length; return wordCount; }

Then i call that function and i pass in $scope.userInput and it gives me an error that says "TypeError: Cannot read property 'split' of undefined"

If i do var wordCount = 'one, two, three'; I get an expected result of 3.

Can anyone tell me if I'm missing something on here?

Thanks in advance!

I'd say the issue isn't with the $scope.numWords function itself, but when you're calling it you aren't passing the proper value. We'd need to see that part of the code the find the problem.
