Custom Conflict Resolution Problem

Hi all,

I
am doing a work were i have to syncronize data between a Publiser
(PC, SQL SERVER 2005), and a subscriber (Pocket PC, SQL CE MOBILE). I
studied lots of articles and i managed to put the syncronization to
work, the problem is in conflict resolution!

The subscriber can´t insert or delet, only update!!



For exmple: I have a table that contais the quantity of a product X,
for example 100 units, this goes to Pocket, but later arrive move 100
units that are increased in the PC, so we get 200 in the PC, (but 100
in Pocket), no problem if i syncronize now (Pocket will have 200 too),
but if remove in Pocket for example 50 units, i've changed the same
column in both Publisher and Subscriber database, if i syncronize now,
i'll have a conflict, the final result should be 150 of product X in
both databases (100 + 100 - 50), but the Publisher wins the conflict
and the final result is 200!



I never worked with stored procedures and in microsoft theres and article called How to: Implement a Stored Procedure-Based Custom Conflict Resolver for a Merge Article (Replication Transact-SQL Programming), but they dont explain it very well and i dont know how to do my own stored procedure and implement it to the merge article.



in my own stored procedure i'll have to do some calculations to get the
result i want, maybe using some table for the additions and
subtractions. (Does the com based Addition resolver do this for me???)



Maybe you have experienced some problem like this, and could help me!

How should i do the stored procedure?

Oh, i tried to use de addiction resolver and the average resolver
of com based but nothing happed, dont know why, i read some stuff and
i think the addition could solve my problem, but it doesn´t work, i read above what you said and installed service
pack 1 for sql 2005, but i instaled and nothing
happened!
When i change to the resolver that the subscriver wins, it works, why addition dont work?

Thanx
