Overlap a small subform over a large subform's free space in the middle

[krag]

I have a main form with 2 subforms (both continuous forms).


For the sake of layout of data, some columns of the large subform should come at the extreme right end.
The smaller subform should fit in the empty space between the left side and right side columns of the large subform.
When I designed this way, the small subform gets completely hidden under the large subform.
Is there any property of subform to program it to bring it above or below another subform?
If there is no way, then only solution for me is to make a third subform for the right side columns of the large subform.
This would involve programming all the control links from the left side main part of the large subform and perhaps it is not impossible but cumbersome.
Look forward to your help if available.

I have to say "no" in answer to your question.

Go with your idea as fix or make big subform Single mode and install smaller subform on bigger one.

Maybe if you made the smaller subform a popup, but you might have to make it modal as well and that likely won't work. AFAIK, Access does not provide for controlling z order (layering) which I think is what you'd need. Did you consider a tab control with pages?

Thanks June7 and Micron.
I guess there is no easy solution but to split the large subform.
Both subforms are pop-up.
I tried modal for small subform but there is no change.
