Draw different scenes with ofGetElapsedTimeMillis() // error on Array bound

sorry its correct! i updated it! thanks MRZL!
weel I have one more question.

on setup i have
sceneNum = 0;

on update

if (timings[sceneNum]<ofGetElapsedTimeMillis()){
    sceneNum++;
    sceneNum = sceneNum % numOfScenes;
}

and on draw
switch ( sceneNum ) {
case 0:
scene00();
break;
case 1:
scene01();
break;
case 2:
scene02();
break;
case 3:
scene03();
break;
case 4:
scene04();
break;
default:
cout << "scene does not exist" << endl;
break;
}

but it doesn't compile and crush it.

Do you know what I missed? or if I am wrong ..

Thanks again
YK
