How can the holiday list be specified for NETWORKDAYS in a macro?

I’m trying to call the NETWORKDAYS function within a macro using the UNO function access service. It works fine when I specify the to and from dates. However, I can’t get the optional Holiday list to work. Everything I try results in an Illegal Argument Exception. How should this be done?

If you are looking for the holidays themselves to be located within the macro, I don’t believe this is possible. The function is looking for a cell range for the list of holidays.

The following works with the holidays listed on a sheet:

function MYNETWORKDAYS(X,Y)       'Where X = Start Date & Y = End Date'
	dim oFunction as variant
	dim oSheet as object
	dim oRange as object
	dim result as double
	oFunction = createUnoService("com.sun.star.sheet.FunctionAccess")
	oSheet = ThisComponent.Sheets.getByName("SHEET-NAME-CONTAINING-HOLIDAY-DATES")
	dim aArgument(2) as variant
	aArgument(0)=X
	aArgument(1)=Y
	oRange = oSheet.getCellRangeByName( "G3:G6" )  'Cell range of holiday dates'
	aArgument(2)=oRange
	result = oFunction.callFunction( "NETWORKDAYS", aArgument() )
	MYNETWORKDAYS = result
end Function

Great, this works!
I had tried both adding an array of dates to the arguments and a range but had improperly extended the range definition with some unneeded and erroneous range address stuff.
