"bigarray[...] is null or not an object"

[Pimonkey]

Okay, I am really having problems with this. The subject is the error I get when running the following function. I have found that it actually does recognize "bigarray[parseInt(tope[ i ])].split(',')[0]", because I have document.writen it. The problem seems to be += the string formate. (The function creates a top ten list of people, based on a large list of people included in another script file)
Other script file example:
var bigarray = new Array(1400);
bigarray[1] = "name ,1,2134,2,.124,.154";
...continues for all 1400 values.

function topeten() {
var tope = new Array;
var i,temp,j,k;
var plac=-1;
for (i=0; i < 10; i++) {
tope[ i ] = 0;
}
for (i=0;i < bigarray.length; i++) {
if (bigarray[ i ] != null) {
for (j=0; j <10;j++) {
if (bigarray[ i ].split(&quot;,&quot[3] > tope[j]) {
plac=j;
break; }
}
if (plac != -1) {
for (k=plac;k<10; k++) {
tope[k] = tope[k+1]; }
tope[plac] = bigarray[ i ].split(&quot;,&quot[1];
}
plac=-1;
}
}
var formate=&quot;&quot;;
for (i=0; i< 10;i++) {
formate += &quot;<tr><td align=center>&quot; + bigarray[parseInt(tope[ i ])].split(',')[0] + &quot;</td><td align=center>&quot; + bigarray[parseInt(tope[ i ])].split(',')[2] + &quot;</td><td align=center>&quot; + bigarray[parseInt(tope[ i ])].split(',')[3] + &quot;</td><td align=center>&quot; + bigarray[parseInt(tope[ i ])].split(',')[4] + &quot;</td><td align=center>&quot; + bigarray[parseInt(tope[ i ])].split(',')[5] + &quot;</td></tr>&quot;; //faults on this line
}
document.write(&quot;<table align=center><tr><td align=center><b>Player |</b></td><td align=center><b>Power |</b></td><td align=center><b>Change |</b></td><td align=center><b>Power Per Hour |</b></td><td align=center><b>% Increase</b></td></tr>&quot; + formate+ &quot;</table><br><center><input type=button onClick='history.go(-1)' value='Back'>&quot;
}

Sorry about the strange variable names...

well yes very strange
can you put an alert( bigarray[parseInt(tope[ i ])].split(',')[5] ) and see what it returns and also if actually that is null or not?by removing that part from ur code and trying

I have tried it and yes it does display the correct value.

Through heavy editing and blind guesses I have got it to work. The problem had to do with the top array, which had problems being undefined.
