I'm having trouble running certain javascripts on my system...

I mean that I am running multiple scripts on 1 page and some of them don't like to work together.

the 2 scripts are:

Code:
<script language="javascript">
snow = false;    // false-rain;   true-snow
snowsym = " * "  //These are the symbols for each
rainsym = " ' "  //You can put images here.
/**************Do not need to change anything below***********/
if(snow){sym = snowsym; speed=1; angle=10; drops=30}
else{sym = rainsym; speed=50; drops=10; angle=6}
movex = -speed/angle; movey = speed; count = 0;
function moverain(){
for(move = 0; move < drops; move++){
xx[move]+=movex;  yy[move]+=mv[move];
hmm = Math.round(Math.random()*1);
if(xx[move] < 0){xx[move] = maxx+10;}
if(yy[move] > maxy){yy[move] = 10;}
drop[move].left = xx[move]
drop[move].top = yy[move]+document.body.scrollTop;
}setTimeout('moverain()','1')}
//Making droplets-------------------
drop = new Array(); xx = new Array(); yy = new Array(); mv = new Array()
if(navigator.appName == 'Netscape'){
ly = "document.layers[\'"; st = "\']" }else{ ly = "document.all[\'"; st = "\'].style"}
for(make = 0; make < drops; make++){
document.write('<div id="drop'+make+'" class=drop>'+sym+'</div>');
drop[make] = eval(ly+'drop'+make+st);
maxx = document.body.clientWidth-40
maxy = document.body.clientHeight-40
xx[make] = Math.random()*maxx;
yy[make] = -100-Math.random()*maxy;
drop[make].left = xx[make]
drop[make].top = yy[make]
mv[make] = (Math.random()*5)+speed/4;
drop[make].fontSize = (Math.random()*10)+20;
if(snow){col = '#E2E2E2'}else{col = 'blue'}
drop[make].color = col;
}
</script>

</head>

<body bgcolor="WHITE" text="#000000" link="#6699FF" vlink="#6699FF" alink="#FF6600" topmargin="1" leftmargin="0" onload="moverain()">
and, or at least whatever is in...
