Default auto number

actually let me rephrase.
i'm talking about "id primary key" and as such its usually comes with
increments.
and there the problem began instead of continuing 666-667-668. it started
98176657-98176658 instead.
and im wondering if there is a way to fix it. but i guess you are trying to
tell me that i shouldn't be
concerned about the primary key number i hope i understood

If you are concerned about duplicates then put a unique constraint on
the Autonumber column; if you think you already have a unique
constraint then double check because there is/has been a bug in Access
where the unique constraint (or is/was is just PRIMARY KEY?) gets
dropped.

You should be unconcerned about the actual values generated; even if
the sequence has skipped 10 million values there will remain more
available values than you could ever use. If you are concerned about
actual values then it is likely you have a design flaw e.g. exposing
Autonumber values to users.
