The following sample Visual Basic for Applications macro makes a call to the non-existent function, "MyFunction". The error listed earlier in this article will occur before the macro begins to run or compile.

   Sub MyMacro()
      On Error Resume Next
      x = MyFunction()
   End Sub

• The Sub procedure or Function exists.
• The Sub procedure or Function is not misspelled.
• The Sub procedure or Function is not declared as Private.
• If the Sub procedure or Function exists in a custom template or document project other than the project in which the calling routine exists, make sure that a reference has been added to the custom template project or document.

  NOTE: You cannot add a reference to a project within a document whose underlying template is the same template as the calling procedure.

Adding a Project Reference

To add a project reference, follow these steps:

1. On the Tools menu, click References to display the References dialog box.

2. The References dialog box shows all object libraries and projects registered with the operating system. Scroll through the list for the project you want to reference. If the template or document project isn't listed, you can use the Browse button to search *.dot or *.doc files. References whose check boxes are selected are used by your project; those that aren't selected are not used, but can be added.

3. Select the Project reference in the Available References box in the References dialog box and click OK.

   NOTE: If a project has not been saved, it appears as "UNSAVED: <Project Name>" and you will be unable to make a reference to it.

NOTE: If the Assistant is hidden, click the Office Assistant button on the Standard toolbar. If the Assistant is not able to answer your query, please see the following article in the Microsoft Knowledge Base:
