SQL Server 2008 - insert trigger not firing - sql

Question

I have a VB.NET application that is creating some INSERT, UPDATE, DELETE statements based on the users selections. I can tell that the SQL is being successfully executed on SQL Server 2008 (I see the table records adjusting appropriately), except one of my insert triggers is not firing.
SQL generated by the application code:
insert into [RECLASS_BALANCE_ADJSTMNT]( PRGRM_REC_ID, DEDUCTN_REC_ID, RBA_YR_PD_NUM, RBA_AMOUNT, RBA_TYPE, ADJUSTER_USER_ID )
values (5504, 8154, dbo.getCurrentYrPdNum(), abs(-21510.70), 'M', '10139638');
insert into [MATCH] (DEDUCTN_REC_ID, PRGRM_REC_ID, YR_PD_NUM, MATCH_TYPE_FLG)
values (8154, 5504, dbo.getCurrentYrPdNum(), 'M');
delete from [POTENTIAL_MATCH]
where deductn_rec_id = 8154
and prgrm_rec_id = 5504;
update [PROGRAM_GL_DTL]
set MATCH_FLG = 'Y', MATCH_FLG_MODIFIED_TIMESTAMP = getdate()
where PRGRM_REC_ID = 5504;
update [DEDUCTION]
set MATCH_FLG = MATCH_FLG + 1
where DEDUCTN_REC_ID = 8154;
INSERT trigger:
CREATE TRIGGER [dbo].[check_partial_offset_status]
ON [dbo].[RECLASS_BALANCE_ADJSTMNT]
FOR INSERT
AS
BEGIN
DECLARE #deductnRecId int;
DECLARE #deductnBalance decimal(18,2);
DECLARE #deductnOriginalAmount decimal(18,2);
SELECT #deductnRecId = i.deductn_rec_id FROM inserted i;
SELECT #deductnBalance = ds.ytd_amt, #deductnOriginalAmount = ds.original_invoice_amount
FROM deduction_summary_updt ds
WHERE ds.deductn_rec_id = #deductnRecId;
IF ABS(#deductnBalance) > 0
BEGIN
UPDATE deduction
SET comment_id = 12
WHERE deductn_rec_id = #deductnRecId;
END --partial matched
IF #deductnBalance = #deductnOriginalAmount
BEGIN
UPDATE deduction
SET comment_id = 6
WHERE deductn_rec_id = #deductnRecId;
END --unmatched
IF #deductnBalance = 0
BEGIN
UPDATE deduction
SET comment_id = 9
WHERE deductn_rec_id = #deductnRecId;
END --fully matched
DECLARE #prgrmRecId int;
DECLARE #prgrmBalance decimal(18,2);
DECLARE #prgrmOriginalAmount decimal(18,2);
SELECT #prgrmRecId = i.prgrm_rec_id FROM inserted i;
SELECT #prgrmBalance = rs.ytd_amt, #prgrmOriginalAmount = rs.reclass_amount
FROM reclass_summary rs
WHERE rs.prgrm_rec_id = #prgrmRecId;
IF ABS(#prgrmBalance) > 0
BEGIN
UPDATE program_gl_dtl
SET comment_id = 12
WHERE prgrm_rec_id = #prgrmRecId;
END --partial matched
IF #prgrmBalance = #prgrmOriginalAmount
BEGIN
UPDATE program_gl_dtl
SET comment_id = 5
WHERE prgrm_rec_id = #prgrmRecId;
END --unmatched
IF #prgrmBalance = 0
BEGIN
UPDATE program_gl_dtl
SET comment_id = 10
WHERE prgrm_rec_id = #prgrmRecId;
END --fully matched
END
GO
I'm trying to understand why the "INSERT INTO [RECLASS_BALANCE_ADJSTMNT].." generated by the application code does not cause the trigger to fire.
I appreciate any help. Thanks!
