Peter,
Here are the problems I found and fixed:

1. Your persistent fields were not instantiated. I did that and, in each case, I did the following:
(a) set the precision appropriate to the definitions in the DDL - viz. below:

CREATE TABLE "TRANSACTION_INFO"
(
"ID" CHAR(12),
"AMOUNT" NUMERIC(11, 2), /* set precision to 2 */
"AMOUNT_2" NUMERIC(3, 2), /* set precision to 2 */
"AMOUNT_3" NUMERIC(14, 4), /* set precision to 4 */
"AMOUNT_4" NUMERIC(5, 4) /* set precision to 4 */
);

(b) set Currency property to True on the first two amount fields and the last
(c) set DisplayFormat property on the third amount field

viz. first time around, I set it to $#0.#### (APP_snapshot1.gif)
second time, I set it to $#0.0000 (APP_snapshot1.gif)

2. I set your Keylinks to ID. (Notice that I had a little trouble with this because you made this a char(12) so your unique id values get stored as "FIRST ", "SECOND " and "THIRD " and a query 'where "ID" = 'FIRST' will not find the row...if you want to use character fields as key fields, make them VARCHAR.)

3. Your button handler had this:

IBOTable1.Fields[0].Value := 4598.58

Naturally, all this did was to change the ID field of the selected record !!

Both of these statements worked fine:

IBOTable1.Fields[1].Value := 4598.58;
IBOTable1.Fields[3].Value := 4598.5813;

I've attached a file (which won't make it to the list) containing the snapshots of the IB_SQL display and the demo app with everything fixed. The monitor output is included too.

A further tip - don't use quoted identifiers in your DDL !!!!!!!!!!!!!!!!!!!!!

Regards,
Helen
