In a form I have the father table and mytable
The the father table has a relation to mytable

I have the fallowing code to add a new item to mytable

use mytable
go bottom
Store mytable.cod to cod1
cod2 = cod1 + 1
append blank
replace mytable.cod with cod2


The problem is: Some times I have repeated cods

It looks like it goes to the bottom
depending to the relation and not to the real
bottom of the table
Anybody knows if this is possible to happen ?
