Digital clock error

I just noticed, when searching a tutorial, that there’s an error in this tutorial. here

J.E. aka IamNot Jubba uses this code:

onClipEvent (load) {
    mon = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Oct", "Nov", "Dec"];

Look very good, who finds the error first… :puzzle:
