SQL Server Trigger Query

I have a trigger written below to update another table when one table is updated.
Basically it works when i update row after row from enterprise manager However when i use a script to update 10 or 20 rows then this trigger does not work. Can any one offer any suggestions on where this issue could be ?


DECLARE @iCount INT
DECLARE @OldValue VARCHAR(255)
DECLARE @NEWVALUE VARCHAR(255)
DECLARE @EQNAME VARCHAR(255)
DECLARE @EQTYPE VARCHAR(255)
DECLARE @TEST VARCHAR(255)
SET @NEWVALUE = 'INIT'
IF (UPDATE(VALUE))
BEGIN
SELECT @OldValue = deleted.value from deleted
SELECT @NEWVALUE = inserted.VALUE,@EQNAME = inserted.EQ_NAME FROM inserted where inserted.attr = 'AreaCfg'
IF (@@ROWCOUNT =0)
BEGIN
RETURN
END
IF ((@NEWVALUE = '') OR (@NEWVALUE is NULL))
BEGIN
DELETE [TABLE-1] WHERE ENTITYID = @EQNAME
RETURN
END
IF ((@NEWVALUE != @OldValue))
BEGIN
SELECT @iCount = Count(*) FROM [TABLE-1] WHERE ENTITYID = @EQNAME
IF (@iCount = 0)
BEGIN
-- No records are available so insert
SELECT @EQTYPE = Typ FROM IP_EQ WHERE EQ_NAME = @EQNAME
INSERT INTO [TABLE-1] (AlarmGroupId, EntityID, EntityType, OwnerId) VALUES (@NEWVALUE,@EQNAME,@EQTYPE,'Production Tracker')
END
IF (@iCount > 0)
BEGIN
-- No records are available so insert
SELECT @EQTYPE = Typ FROM IP_EQ WHERE EQ_NAME = @EQNAME
UPDATE [TABLE-1] SET ALARMGROUPID = @NEWVALUE WHERE ENTITYID = @EQNAME
END
END
END
