More Macro / Addin Troubles

I want to create an addon so that I can distribute a macro to others. I'm doing the following:

1) I open a brand new work book, push alt + f11 to go to VB editor, and insert my code in a new module. I compile it.
2) I insert the following code in the "ThisWorkBook" code section and compile it. The point of this code is to add a tool bar to run my macro when a worksheet opens, and delete it when it closes:

Private Sub Workbook_Open()
AddNewToolBar
End Sub

Private Sub Workbook_BeforeClose(Cancel As Boolean)
DeleteToolbar
End Sub

Sub AddNewToolBar()
Dim ComBar As CommandBar, ComBarContrl As CommandBarControl
On Error GoTo ErrorHandler
On Error Resume Next
CommandBars("Count Bins Toolbar").Delete
Set ComBar = CommandBars.Add(Name:="Count Bins Toolbar", Position:= _
msoBarFloating, Temporary:=True)
ComBar.Visible = True

Set ComBarContrl = ComBar.Controls.Add(Type:=msoControlButton)
With ComBarContrl
.Caption = "countBins"
.Style = msoButtonCaption
.TooltipText = "Run Macro1"
.OnAction = "countBins"
End With
Exit Sub
ErrorHandler:
MsgBox "Error " & Err.Number & vbCr & Err.Description
Exit Sub
End Sub

Sub DeleteToolbar()
On Error Resume Next
CommandBars("My Toolbar").Delete
End Sub

3) I save it as an addin and place it in the addin folder.

When I try to use it in another work book, the toolbar opens up fine, but when I go to click on the macro I get a weird message:

'countbinstoolbar.xls' could not be found. Check the spelling of the file name and verify that the file location is correct. If you are trying to open the file from your list of most recently used files on the File menu, make sure that file has not been moved, removed or deleted.'

I should say that 'countbinstoolbar.xls' isn't even the name of the addin (countbins) and was a file that I created a couple of hours ago when I was playing with that I eventually deleted. So I have no idea why that's on there.

When I try to open this on my friends computer, nothing happens, the toolbar doesn't even get added. Does anyone know what I could be doing wrong? We're both using excel 2003 btw.

I'd hate to sound like a jerk but this is a cross post. The Excel help community takes this seriously (as I learned the hard way). I figure this is completely incidental (as it was in my case), but if people find out about this, you'll most likely receive no help, get your thread locked/deleted, and/or be banned. Theres good reason for this if you think about it. All you have to do when you do cross post is note (on all forums this questions is on) that the question can also be found in other forums and post links to that thread. This way, should someone invest time in figuring out your solution, they know that it already hasn't been addressed in other forums already and that they wasted their time.

Also, you may want to try to use Tools-References command in VBE.

the Toolbar code should be in the addin
