Check for new record in Network app

I guess our ideas are not sinking in, because the potential solution I and koolsid posted can guarantee that. Either our ideas are not sinking in or both of us are way off base regarding understanding the situation.

If the following scenario creates a problem, then the posted non-timer solution by koolsid and myself may not work as is
1. You have 3 pcs up and running, each wrote blank records to the db & each are waiting for customers
:: Pc1 shows nr 101, Pc2 shows nr 102, Pc3 shows nr 103
2. A customer comes to pc #2 and will get customer number 102. Record is added to db & now pc2 shows nr 104
3. A customer comes to pc #3 and will get customer number 103. Record is added to db & now pc3 shows nr 105
4. Customer finally comes to pc #1 after 10 more customers have visited pc #2 & #3. This customer will get nr 101 and the pc will now show #115 after updating the db.

Does it really matter which customer ID is used at any one time, as long as no number is duplicated?
