How to select dynamic checkbox from web dropdown

[QA_Newbie]

Here is what i did.

Code:

Function xx()
Dim yy
yy=Array("1","2","3"...., "19")
Randomize
SelectedProperty=yy(Int(Rnd*19))
Print("selected:"&SelectedProperty)
xx=SelectedProperty
End Function

I call this function in my script. Everytime the script is run it chooses the random property from the list.
