I totally get what the OP wants, code-wise, I just cannot help make it happen, but perhaps I can put it in my terms and help someone more knowledgeable than me help him.
What he is saying, is that when a variable is deleted from within the array, he needs the entire array re-ordered (sorted) and moved up a notch to account for the now deleted variable. So, if A,B,C,D is the array with positions 1,2,3,4 and you delete array variable 2 It will now look like this: A,C,D and the array numbers are now: 1,3,4 He needs it to be A,C,D and 1,2,3 The C is now 2 and the D is now 3, so on and so forth across however large the array is. Now, does one simply re-write the array once the deletion is made? Not sure. Note - if this is for a database and you are dealing with IDs, then DO NOT RE-ORDER ANYTHING - you will break the database (well, not literally until you do a SAVE - then you really will break it). Just leave it as is. Databases can eventually be re-ordered (re-indexed) once they are too large and riddled with holes, but until then, just leave it alone.
