varchar entry of 5118 causing SQL Server stored procedure to fail - sql-server

Question

and thanks in advance
I have a very basic stored procedure that inserts a row into a table. It has been working flawlessly until today
Here is the script
(
#emp varchar(16),
#logdate date,
#logtime time,
#term char(20),
#SSID char(16)
)
AS
INSERT INTO AccessLog (EmployeeID, LogDate, LogTime, TerminalID, InOut, ChangedBy)
VALUES (#emp, #logdate, #logtime, #term, 3, #SSID)
When the string of 5118 is passed to it the insert will fail. There are several triggers that fire after this insert finishes.
Here's the strange part. You can pass it anyother number for the #emp variable and it works just fine, but pass it 5118, it fails.
The error I receive is below:
Msg 241, Level 16, State 1, Procedure UpdateTimeWorked, Line 27
Conversion failed when converting date and/or time from character
string.
Here is the procedure that is failing – the highlighted line is Line 27
TRIGGER [dbo].[UpdateTimeWorked] ON [dbo].[TimeLog]
FOR UPDATE
AS
SET NOCOUNT ON
DECLARE #ID int;
DECLARE #RCDIDIN int;
DECLARE #RCDIDOUT int;
DECLARE #ComboIn datetime;
DECLARE #ComboOut datetime;
SELECT #ID = ID FROM INSERTED;
SELECT #ComboIn = LoginCombo FROM INSERTED;
SELECT #ComboOut = LogoutCombo FROM INSERTED;
SELECT #RCDIDIN = RCDIDIN FROM INSERTED;
SELECT #RCDIDOUT = RCDIDOUT FROM INSERTED;
**IF ( UPDATE(LogoutCombo))**
BEGIN
IF (#RCDIDOUT != 0)
BEGIN
UPDATE TimeLog
SET LogOutRND = (select CAST(dbo.roundtime(LogOutRND,0.25) AS TIME))
WHERE ID = #ID
UPDATE TimeLog
SET LogOutComboRND = CAST(CAST(LogOutDate AS DATE) AS SMALLDATETIME) + CAST(LogOutRND AS TIME)
WHERE ID = #ID
UPDATE TimeLog
SET TimeWorked = dbo.gettime(DATEDIFF(ss,LogInComboRND,LogoutComboRND))
WHERE ID = #ID AND LogInEntered = 1 AND LogOutEntered = 1
UPDATE TimeLog
SET TimeWorked = (select CAST(dbo.roundtime(TimeWorked,0.25) AS TIME)), Rounded = 1
WHERE ID = #ID AND LogInEntered = 1 AND LogOutEntered = 1
END
END
IF ( UPDATE(LoginCombo))
BEGIN
IF (#RCDIDIN != 0)
BEGIN
UPDATE TimeLog
SET LogInRND = (select CAST(dbo.roundtime(LogInRND,0.25) AS TIME))
WHERE ID = #ID
UPDATE TimeLog
SET LogInComboRND = CAST(CAST(LogInDate AS DATE) AS SMALLDATETIME) + CAST(LogInRND AS TIME)
WHERE ID = #ID
UPDATE TimeLog
SET TimeWorked = dbo.gettime(DATEDIFF(ss,LogInComboRND,LogoutComboRND))
WHERE ID = #ID AND LogInEntered = 1 AND LogOutEntered = 1
UPDATE TimeLog
SET TimeWorked = (select CAST(dbo.roundtime(TimeWorked,0.25) AS TIME)), Rounded = 1
WHERE ID = #ID AND LogInEntered = 1 AND LogOutEntered = 1
END
END
GO
I am at a total blank to come up with why this is not working.
Anyone have any ideas?
Like I stated, pass it any other entry for the #emp and it will run fine. I can even pass it ‘5118’ and it will work, but not 5118.
