no such object

[hershrev]

Hi every one
I have a script in a stack
on openStack
    "put  revOpenDatabase("PostgreSQL",field 
"ip_address","test","postgres","xxxxxxx")into field "myDBID"
end openStack
  working fine , when I call it from a substack,(call "openStack" ) the 
compiler comes up no such object.
