Parameter field

Hi everyone,

I am making a report in which I have two parameters field. The first one is simple i just want to choose a project from a list of project. In the second one I want to choose multiple activities from that project. I just can't find a way to get that second list to be linked with the first choice.

In the second list I get all the activities available in my database but I want to display in that list only the activities related to the project I have chosen in the first parameter.

Hope i am clear enough.

Thanks in advance.
