Hello Donald,
I think you can chalk this one up to a copy and paste error!

Since CreateDataAccessObject is an mmBusinessObject method, it should have been pasted inside your ABusinessObject's class declaration and should look like this:

public class ABusinessObject : mmBusinessObject
{
	/// <summary>
	/// Constructor
	/// </summary>
	public ABusinessObject()
	{
		this.DatabaseKey = "FX";
		this.DataAccessClass =  "vistadb";
	}

	protected override OakLeaf.MM.Main.Data.mmDataAccessBase CreateDataAccessObject(string dataAccessClassName)
	{
		if (dataAccessClassName.ToLower() == "vistadb")
		{
			return new mmDataAccessVistaDB();
		}
		else
		{
			return base.CreateDataAccessObject (dataAccessClassName);
		}
	}

}

That's why you were getting that error. The compiler was telling you that the code was not in a class declaration. If you look at it again, you'll see the method was inside the namespace block instead.

Hope that makes sense,
