Hi,

From automation script 2 you can use subscript = engine.PrepareSubscript (ref to Help) which will return a SubScriptOptions object

You can then use this object and call subscript.SelectScriptParam (ref to Help) before calling the StartScript method as illustrated in the example available on the first link help page

In the end you should have something like this

var subscript = engine.PrepareSubScript("MySubscript");
subscript.SelectScriptParam("myScriptParam1", "myValue1");
subscript.SelectScriptParam("myScriptParam2", "myValue2");
subscript.StartScript();
