Using TableSync@HQ

Hi Guys I was trying to use the Table Sync table of the HQ to synchronize user tables at the Stores(To download to Stores). To my surprise i found the following: 1. I cant select stores to which i need to download data,it gets downloaded to all stores unless i edit so on the Worksheet. 2. Though Data gets pushed to the User tables at the Stores,The HQID fields at the store for the User tables are 0 ,which were supposed to be the Ids of the respective tables @ HQ. 3. To most funny thing,each time after an updation was made to a User table on the HQ and 401 Worksheet was run,the entries in the Store user table gets duplicated, there is no primary/foreign keys,but it does have the Identity field. This happens to only one User table while the others get synchronized fine.I beleive i did the settings common for all user tables to be synced. Can someone help me out on the above plz. Thanx in advance.... Zak
