(A): The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time.
I want to update fields rsData!Num = i , can you help me ?

Your problem is that u have a number of j "Addnew" commands and only one Update...The number shoud be the same so i think that putting also rsData.Update before Next will solve your problem

Thread moved to Database Development forum (the "VB6" forum is meant for questions which don't fit in more specific forums)

corneagigi is correct about that, and note that it applies to both of your loops - for the second loop the .Update should be before the .MoveNext
