  Sample input:
DailySerial ( id ; 2 ; "" )
DailySerial ( id ; 2 ; 1 )
DailySerial ( id ; 2 ; 2 )
  Sample output:
2005122601
1226200501
2612200501

  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

This custom function can be used for:

1) Autoenter a serial number that increments daily
2) the format of the serial number is essentially: YYYYMMDD##
3) the serial number may have how many digits (#) you choosed
4) the format can be specified, so to have:
format = 1: MMDDYYYY##
format = 2: DDMMYYYY##
format = "": YYYYMMDD## <--this is the default result

The Auto-Enter field must be setted to always evaluate;
the custom function isn't recursive, so you can use it as a simple calc;
the custom function will work only with FMP8 and above.

This almost worked.

Output record 1: 070120131
Output record 2: 0701201332
Output record 3: 07012013333
Output record 4: 070120133334

Any ideas where this went wrong?

How did you enter the function?
IOW, which are the values of your parameters?

AEfield: DailySerial ( Serial Number ; characters ; "" )
digit: 1*
format = ""

* I have since discovered that this was wrong and have changed it to a "2"

Now I am receiving the following:
2013010801
2013010801
2013010801

note that It is not advancing to the next value.

Okay, false alarm and I have re-implemented the custom function and it now works well.

Thank you!
