I cant call a subroutine that is located in my form from an external module.......like

Form Code:
VB Code:
  1. Public Sub Hello(byval strString as string)
  2. Code Here
  3. End Sub

Module Code:
VB Code:
  1. form1.Hello("Hello")

what is wrong..............is there another syntax? because in the form i can do

VB Code:
  1. Module1.(some subroutine)
??????
