ActiveX & VBA

I have an Activex Control that displays a diagram on the Initialize event of the control.

I can place the control on the form of a MS Access 2000 Database and it works fine, but, when I place the same control on an Access report it does not work.

I am using the same code under the Open event of the report as I do for the Open event of the form.

Why doesn't it work?

Thanks
