Dynamic dependent data validation list

Hi all,

I got stuck when trying to get a dynamic data validation list who is dependent on another data validation list. I would really appreciate some help here.

I've uploaded a workbook that hopefully illustrates what i am trying to accomplish. In a summary: I have some companies as a header in a couple of columns. Under each company there are contact persons for that company.

I now have a dynamic drop down list with all the companies and need to have a drop down list that is dynamic and will change depending on whats chosen in the drop down list that contains the company names.
