Calling Click event of another form

I have an Access 2007 application in which I'm creating a custom ribbon.  I

have a callback module in which there is a routine called onOpenForm. 
Within 
the routine there is a select case statement where code is executed based
on 
the calling ribbon button.  I'm having trouble with one of Case statements

where I need to both open a form and call the click event of a command
button 
on the form.  Here is the relevant code:

        Case "btnEnterProject"
            If (CurrentProject.AllForms("frmProjects").IsLoaded) Then
                Forms!frmProjects.SetFocus
                Forms!frmProjects.cmdAddProject_Click
            Else
                DoCmd.OpenForm "frmProjects", acNormal
                Forms!frmProjects.SetFocus
                Forms!frmProjects.cmdAddProject_Click
            End If

When I run the code I get an error message #2465, "Application-defined or 
object-defined error."  If anyone can tell me what I'm doing wrong here, I

would be very appreciative.
