Deleting not working

Question

below i've attached my partial code. i didn't include my
entire code because it's 334 lines long. if i need to do that to
get this solved though, i will... just let me know.
in the for loop below, i assign 3 functions to a newly
attached movie clip. one function for each of the three major
button states (onRollOver, onRollOut, onRelease). i delete and
reassign these functions by clicking a different movie clip
(openGrid3 and closeGrid3). if i don't pass over the "item" movie
clip, and then open grid3 (openGrid3), all works as expected.
however, if i pass my mouse over the "item" movie clip, then open
grid 3, none of the states get deleted. what am i doing wrong?

Answer 1

i wanted to mark this as resolved, to preserve the integrity
of these forums that i use and appreciate so much. i discovered my
problem and the solution is below. looking back on this post now, i
bet this made no sense to anyone, as i had diagnosed the symptoms
incorrectly and this one really is hard to help without seeing the
flash movie playing. here's the solution that fixed it for me
though...
first the problem did not occur because the user passed over
the item. when openGrid3 ran, the item button states were deleted,
but you'll also see that the action that ran the openGrid3 function
was deleted. it was then changed to closeGrid3, however closeGrid3
did not delete itself and reassign openGrid3, so on the second pass
around, none of the items had their button states deleted. i added
these lines to the closeGrid3 and closeGrid4 functions....
delete grid*.panelButton.onRelease;
grid*.panelButton.onRelease = openGrid3; //* = which grid, 3
or 4
