set StopOnError via script

I am trying to write a simple script that runs each time a project starts. It is to loop through the test items and shut off the StopOnError property.

 

Here is the code I have right now that doessn't work (JScript):

 

var i;

for(i = 0; i < Project.TestItems.ItemCount; i++) {

    Project.TestItems.TestItem(i).StopOnError = 0;

}

 

This throws and error: "Invalid number of arguments or invalid property assignment"

Is this specific task even possible?
