Uncaught Reference Error: printSongs is not defined

I keep getting Uncaught Reference Error: printSongs is not defined on line 22. Any help would be appreciated.

var playLists = [ ['Help', 'The Beatles'], ['Beautiful Day', 'U2'], ['Rose Parade', 'Elliott Smith'], ['Two Babies in Michigan', 'Fruit Bats'], ['Clementine', 'Elliott Smith'] ];

function print(message) { document.write(message); }

function printList( songs ) { var listHTML = '<ol>'; for ( var i = 0; i < songs.length; i += 1) { listHTML += '<li>' + songs[i][0] + 'by ' + songs[i][1] + '</li>'; } listHTML += '</ol>'; print(listHTML); }

printSongs(playLists);

Hi Andrew,

When you defined the function you called it printList and not printSongs so when you go to call it at the end it cannot find the function. Either change the name of the function to printSongs when you declare it, or in the last line call it using printList(playLists)
