This is my Custom Function and I want to edit it


I am trying to get a unique serial ID which resets every year in the format (201301 - 201302... 201401 so on). But when I tried this code above I am getting the ID as 201301, 2013001, 20130001 and so on) can you help me here to get this right.
Thank you

If you're using server, changing the year string to:

year = Year ( Get ( CurrentHostTimeStamp ));

will help prevent individual machines from providing an incorrect year.

Let ([
todayyear = Year (Get (CurrentDate));
todaymonth = Month (Get (CurrentDate));
lastID = GetNthRecord ( AEfield ; Get (TotalRecordCount ) -1);
lastMth = Left (lastID ; 2) ];

Right ( "0" & todayyear;2) & Right ( "0" & todaymonth; 2 )
& Case(
todaymonth ≠ lastMth or Right ( lastId ; digit ) = 10^digit -1; Right ( 10^digit ; digit-1 ) & "1";
SerialIncrement ( Right ( lastID ; digit ) ; 1 )

Why my answer is like that after I create the script.When I trigger new record, the answer like below.

Maybe that you haven't unchecked the box: "do not evaluate if..." in the options of your auto-enter field.
