When you want to add a record to a table you have to exclude the last row deleted. 

So lets say your table have 10 rows with the deleted row to a total of 11.
you have to exclude the deleted row in your array();

sample:

table is :

<?php
 $row
($PID,$SID,$RID,$CON,$COM,$AD1,$AD2,$CIT,$STA,$ZIP,$deleted);
 
$record=array($PID,$SID,$RID,$CON,$COM,$AD1,$AD2,$CIT,$STA,$ZIP,);
 
$db dbase_open($db_path_and_file,2);
 
dbase_add_record($db,$record );
 
dbase_close($db);
?>

This will work.
