Strange Problem

[developerno1]

I've a database application where i can add the records of the workers of a place etc. Now im encountering a strange problem while adding data in one of the table. the problem is that when i add records, ideally it should be added as employee1 followed by employee2 then 3 and so on... It works perfectly upto record no 13. i.e employee 2... 3...4...----11-12-13 but after 13 the 14th record is added before record no1 1. then 15th after it.. i.e. 14-15-1-2-3----13.
This is kinda weird and im not able to find out why?? There's no such code to do it and i cant imagine why's dis happening... Hope someone else has had something like this before...!!!!

Also the database shows dem in correct order i.e 12--13--14 and 14 doesnt appear in the starting!!!
