Huh??? If you have entries for: name[0], email[0], sex[0] name[1], email[1], sex[1] name[2], email[2], sex[2] ... and then delete the entry containing sex[1], why wouldn't you just end up with name[0], email[0], sex[0] name[2], email[2], sex[2] ... ??? Unless, of course, what you have is name[], email[], sex[0] name[], email[], sex[1] name[], email[], sex[2] ... ... in which case, don't do that! If it's important to you that the indexes match across name[], email[] and sex[], then you must supply them explicitly for every field in the group -- if you name some of the fields with [], and some with explicit [1], [2] indexes, you're setting yourself up for exactly this kind of mismatch problem when you come to delete (or insert!) entries.
