Can a macro in the personal.xlsm be called from within an open macro that is in the workbook?

[rltidd27]

I have this simple macro in the Personal worksheet and it works fine when run.
I then put this macro into the Open Macro I want to use when opening the file
'msgbox testing
Sub messageBox()
MsgBox ("Ok to here")
End Sub

Here is the open macro.
Private Sub Workbook_Open()
'this macro is to unprotect and show all sheets

'Sub Open_Setup()

'Call UnProtectAllSheets

'Call UnhideVeryHiddenSheets

'Call Switch_to_Quote

'Call Unhide_AD_and_AE
Call messageBox

End Sub

Upon opening, here is the error message I receive:
Microsoft Visual Basic for Applications
Compile error:
Sub or Function not defined

Anything that I try to call within the WorkBook Open macro to the personal workbook, will not run.
I am presuming that you can not call a macro in the Personal workbook from the open macro.
Any help is appreciated.

Try

Application.Run "Personal.xlsb!messageBox"

It looks like my reply is gone.
Thanks so very much for your help!
This worked perfectly and solved a problem I have been working on for some time.
Have a GREAT day!
