sql server report service 2008 error

Question

'The tablix 'Table1' has a detail member with inner members. Detailed members can only contain static inner memmbers.
  I am getting the above error message in sql server reporting service 2008 when do the following when there is nothing on the design surface
(creating a report without the report wizard):
   a.  I drag on a 'list' item from the tookbox onto the 'design surface'.
   b.  I drag a few columns from the dataset onto the 'list' item.
   c.  I then place a 'table' toolbox item within the 'list' item.
   d.  I then preview the report. 
  I think I want the control 'row' group to work, but I am having trouble getting that setup. 
  Basically what I am trying to do overall is have:
  1. The report parameters work,
  2. I want the table to redisplay every time I come across a new secondary level control break,
  3. I want to use the report parameters to only select a of the 'general' population.
 Note: I have also used the report wizard and I can get each of the following items to work alone but not together:
  1. I can get the report parameters to work,
  2. I can get the the report to display everytime there is a change in the change in the control group.
Basically I want to be able to do something like the following:
1. In the parameters, I want to be able to select the country I want.
2. I then want to display a fresh copy of the report everytime the state/province changes.
Let me know what combination of solutions may work here.
