I have a button (myCloseBtn) and when clicked it runs a function (removeFull) to remove a child (full_mc) from the stage along with some others (full_description) (full_caption) (full_price). This works fine!
I also want to remove two other button instances/children (mySpinBtn) & (myCloseBtn) but I can’t find a way of making it work.
I am a newbie at doing this sort of thing (ie. loading things at Runtime and Children etc.)
Could anyone help me please!???

I just get this error:
TypeError: Error #2007: Parameter child must be non-null.

Thanks for looking at it - I’m a bit lost to be honest and could really do with some help???
