This is how it works, your code needed some edit.
Thanks for your help
Code:
Set chObj1 = Description.Create
[b]'chObj1("micclass").Value= "LINK"[/b]
chObj1("html tag").Value ="A"
chObj1("class").Value ="arrow_normal"
objCount1 = Browser("IDD Portal Login").Page("IDD Portal")[b].Frame("frameLeft")[/b].ChildObjects(chObj1).count
