When I am using this code, still its not working. WHen I add "document.getElementById("hours").innerHTML = dtObj.getHours();" , code stops working. If this line is not added in javascript, all alerts upto 4 are working. So there is something wrong with this code, which stops everything. What can be wrong with this ?

Whats the difference between two codes ? Bottom one is working, top one is not. I wouldlike to know the bug, this thing keeps happening.

Thanks

Surely there must be something in the Javascript console if your Javascript code ends unexpectedly?

Not always. De-referencing an undefined values often results in a silent failure. It's sometimes infuriating.

So, what has been done to verify that the items that are being dereferenced are not undefined?

I have re-written the code in a new file and its working.

Now this is my question. Where shall I start from for such a bug ? Now in this case, as you mentioned " what has been done to verify that the items that are being dereferenced are not undefined? " How can I verify this ?

Thanks
