Wayne,

Since you have complex containers, another way to go is to use a grid, you can preload a column with one of each of your Q&A containers and then use something along the lines of:

with this.grid1
   with .Column2
      .DynamicCurrentControl = 'iif( i1 = 1, "cnt1", iif( i1 = 2, "cnt2", iif( i1 = 3, "cnt3", "cnt4" ) ) )'
      .Sparse = .t.
   endwith
endwith

which would set the right container based on the question type.
