How can I calling a Subroutine from Microsoft Access?

I have a subroutine in Microsoft Access that is not a macro (it is contained in a module.) I searched and found this previously but it is used for macros. http://www.mathworks.com/matlabcentral/newsreader/view_thread/34936

I also looked up the application.Run method http://msdn.microsoft.com/en-us/library/office/ff193559.aspx

My access subroutine in the module is as follows.

Public Sub Test()
    MsgBox "Hello", vbOKOnly
End Sub

My MATLAB code is as follows

Access = actxserver('Access.Application');
invoke(Access,'OpenCurrentDatabase','PathName');
invoke(Access,'Run', '"Test"');
invoke(Access.DoCmd,'Quit');

Then I get

Description: You made an illegal function call.

Error in ==> TestScripts at 3 invoke(Access,'Run','"Test"');
