SAVE NEW DATA INTO ANOTHER TABLE

I am not much of a programmer so i rely heavily on the sollutions that PHPR gives me

SO this is what i am doing

I want when i add a record in table "tamio" some of the fields to be added in table "litourg"

I used a before record added event like this
//** Save new data in another table ****

global $conn,$strTableName;
$strSQLSave = "INSERT INTO litourg (littype, litinfo) values (";
$strSQLSave .= $values['tamtype'].",";

$strSQLSave .= $values['taminfo'];
$strSQLSave .= ")";

db_exec($strSQLSave,$conn);
return true;
// return true if you like to proceed with adding new record

// return false otherwise
litourg littype and litinfo are the other table and fields

and tamtype , taminfo are the fields from tamio that i want to be copied to litourg
BUT

when i add a record it gives me an error except when the values of tamtype and taminfo are numbers
Specificly the error that i get is this
