assigning two child bands?

I want to display optional additional information to MasterData.

One is a comment that I placed in a child band. The user can choose before report generation if he wants to display this information.
If he choses not, the child band will not be displayed. This works.

I want to do the same with photos that are connected with each masterdata row but even though I can add a 2nd child band to the report, I can only assign one child to the masterdata band.
Is it not possible to assign two childs to one masterdata?

How to proceed?

    ChildBands can only be chained to each other what you probably should be doing is setting the visible property for the child

    procedure MasterData1OnBeforePrint(Sender: TfrxComponent);
begin
  if <Line> mod 2 = 0 then MasterData1.Child := Child1 else MasterData1.Child := Child2;                                                                                                                                  
end;

    Thanks for your advices but they do not adress my problem.
    The two child bands shall be independent from each other. That means that the user should be able to activate child band 1 or band 2 or also both.

    When I set Child2 as child of Child1, Child2 will be invisible when Child1 is opted out.
    Also, setting one child instead of the other doesn't help as this will not allow to show both band.

    Currently this runs smoothly with Quickreport which I am working to convert to FR.
    In Quickreport I use a Subdetail and a Child band but FR does not allow me to use Subdetail.
    It keeps on telling my that the band is in the wrong place.

    lets solve the real problem
    place your header footer bands in ordered pairs above and below each data band
    h1
    md
    fi
    h2
    det
    f2
    h3
    sd
    f3
    or set free band placement prop

    Add band. Add Child1 and Child2. Set Band.Child = Child1, Child1.Child = Child2, Child1.PrintChildIfInvisible = True

    Use TfrxMasterData band. Read FR manual, see FRDemo
