[gunovanengel]

Hi,

I am trying to change the dataSource with the js script below.
I keep getting the error Object expected code 800a138f
What am I doing wrong

Regards
Guno

AB = CreateObject("Broker.Application");
sts = AB.Stocks();
Qty = sts.Count;
for( i = Qty - 1; i >= 0; i = i - 1 )
{
  sts.DataSource = 0;
}
