In Adobe Acrobat Javascript, how do I search an entire PDF for all instances of amounts over 10,000?

I wrote this:

for (var p=0; p<this.numPages; p++) {
    for (var n=0; n<this.getPageNumWords(p); n++) {
        var w = this.getPageNthWord(p, n);
        if  (w >= 10000) {
   console.println(w);
} else if  (w <= -10000) {
   console.println(w);
}

    }
}

However, it keeps giving me this error when I run it:

SyntaxError: syntax error
1:Console:Exec
undefined

Does anyone know what I'm doing wrong?
