I am having a problem getting two javascript snippets to run on a single
html document. Whichever one is loaded last (further down in the html doc)
runs fine. I am not any kind of javascript expert and would appreciate any
help here.

Thanks

-------------------------------------------

The two examples of the html doc are here:

http://216.122.129.151/javascript-conflict1.html

http://216.122.129.151/javascript-conflict2.html

--------------------------------------------

Alternatively I reproduce the two snippets here.

***********************************

Problem (fairly simple/obvious) was having two "onload" commands - only one allowed - solved by combining the two triggers invoked by window.onload
into a single function

window.onload=fillup
window.onload=start_ticking

becommes

window.onload = function()
{
fillup();
start_ticking();
}
