Would there be a way to dynamically change the "select" mode to <%list.listB.nextvalue%> with an /ontrialbegin clause? Is there another way? I could always hard code them but since my pictures can be either on the left or on the right, from category X or Y, and finally from pool A or B of a category, this would yield 2^3 picture elements with basically the same code which just seems like very bad programming to me.
