Global Subs and Functions VB.NET

I have a couple of functions I would like to be available across my classes and forms.
Error Logging, Progress Logging, Send Mail and a Message Box helper for debugging.

I know I can define these on my main form called "Main" and then call them in a class as Main.SubName() - but being a lazy bugger, I want to be able to just call them as SubName() without the main form name.

I created a new class here's my code:

Public Class myHelpers
   
 'Message Box Helper - for debugging 
    Public Shared Sub mbHelper(ByVal lineNumber As Integer, ByVal Task As String, ByVal message As String, ByVal additionalInfo As String)
        Dim title As String = "Debug Information"
        Dim messageText As String = "Line Number: " & lineNumber & vbCrLf & "Task: " & Task & vbCrLf & "Message: " & message & vbCrLf & "Additional Info: " & additionalInfo
        MsgBox(messageText, MsgBoxStyle.OkOnly, title)

    End Sub

End Class

Select allOpen in new window

In my forms and classes I imported myHelpers - but that did not work, mbHelper is not recognized.

Any ideas what I'm missing?  Sorry if this is a simple problem - but I really appreciate the help!!!
