Filter with combo boxes (1 Viewer)

Hi Guys

I tried a couple of things already but I just can't figure it out how the forms or controls are connected together.

Here an example what I want to achieve:

I want to have a first combobox which shows me all the customers. As soon as I choosed a customer I want to show in a second combobox all reports regarding to the customer. And as soon as i choose the report in the combobox it show it to me in a subform. So how can i pass the info from one control to the other???? If you need VBScript code for it is also fine. Please with a small example....

Thanks for any tip

Cascading combo boxes. Tonne of examples around the patch.

I've probably poasted 3 or 4 links to good tutorials the past 5 days alone on this subject.
