>>Is there a Sql Command like---> Update Inventory Set Balance = Balance +5
which replaces whatever Balance is in Sql with the Balance + 5
If there is, I think that would work fine
Yes, there is.
I add a field to all the SQL Tables called lckstat char(1) and lckuser char(4).
When someone grabs a row for update, I set lckstat to 'L' and clear if when finished.
If it has 'L' in when user B goes for, I tell them that user A has it locked.

....User A : Update Inventory Set Balance = Balance +5
....User B: Update Inventory Set Balance = Balance +7

I have only ever used a sSql Update as:
Update Inventroy Set Balance = X which replaces the Balance with X
But in my Case, Say I am User B, when i Initially took the Balance it was 100, and now I am replacing it with 100 + 7
but User A has already increased it to 100 + 5 = 105
