Well I feel like a serious clutz right now =_=;
I had thought that would work, so I turned off solid on the second object,
however it still went through the floor.
I kept fiddling through menu's looking for a possible solution,
and at some point I realized when previewing the project and
the object went through the floor after I had turned solid back on,
that I had set it's collision setting to 'none'.
However because I had already set it back to a solid now, I hadn't
suspected that it would in fact collide with the ground with solid off,
and just went back to hoping to find a solution elsewhere.
However, I only realized all the above after you had told me it would work,
and I tried again successfully.
Thanks for the quick reply, greatly appreciated :).
