After Effects Number Generator

I need a number counter with comas that goes up to at least 100,000,000. Preferably infinitely. The "numbers" effect in AE only goes up to 30,000 (without a coma). This expression:

var num = effect("Slider Control")("Slider")

num = Comma(num);

[num]

function Comma(number)

{

number = '' + Math.round(number);

if (number.length > 3)

{

var mod = number.length % 3;

var output = (mod > 0 ? (number.substring(0,mod)) : '');

for (i=0 ; i < Math.floor(number.length / 3); i++)

{

if ((mod == 0) && (i == 0))

output += number.substring(mod+ 3 * i, mod + 3 * i + 3);

else

output+= ',' + number.substring(mod + 3 * i, mod + 3 * i + 3);

}

return (output);

}

else return number;

}

(located here: CreativeCOW ) is limited by the slider which only goes up to 1,000,000, but it does enable comas. Does anyone have a suggestion on how to make this work?

Thanks!
