Using BIA_RegisterCalcValidationProgram in Excel AUTO_OPEN macro

Question

The documentation for the Spreadsheet Addin, section 5.5, states:
"You can include the BIA_RegisterCalcValidationProgram() macro in the auto_open procedure to automatically register the program for calculation and validation when a workbook is opened."
I have created an AUTO_OPEN() procedure in Excel, and stored it in my personal.xls. I also have the Oracle BI add-in starting automatically.
However, when I start Excel, I get a Microsoft Visual Basic Compile error: "Sub or Function not defined", and it's highlighting the BIA_RegisterCalcValidationProgram function in the debugger.
I can use that function just fine by calling it from a button, but that happens after Excel has successfully started. I want to register the program when Excel opens, as the documentation says I can.
Here is my AUTO_OPEN procedure, as stored in personal.xls:
Sub AUTO_OPEN()
Dim query_id As String
Dim calc_id As String
Dim s As String 'Generic string return value
query_id = "Q.BUDGET.2" 'Query name in worksheet
calc_id = "dai.daiprog!BUDGET.CALC"
s = BIA_RegisterCalcValidationProgram(query_id, calc_id)
End Sub
Please note that this exact same code works just fine as a standalone macro. It's only when used in the Auto_Open that it fails.
Am I missing a step somewhere?

Answer 1

Incidentally, if I use this as the AUTO_OPEN macro in personal.xls, it works just fine, so I'm pretty sure AUTO_OPEN is the right place to be:
Sub AUTO_OPEN()
MsgBox ("Hello There")
End Sub
