Hi all,
I changed something in StockListDemo code, but it has error : "duplicate values" when show on default.html file, just only this column - offer volume (mark by red color, see image below). I verified my code (c# code), it hasn't problem.

Here my data :

//offer volume values
ask1vol[] = {10, 21, 34, 56, 45, 64, 78, 56, ...}

Here my error :
-----


Can anybody help me?

Thanks!
