Formats an amount. Needs my other custom function formatN

Sample Input:
formatAmount( 12345678.9 ; "," )
Sample Output:

 Then copy & paste into FileMaker Advanced's Edit Custom Function window.


I think the function is very easy to read. Can handle amounts of any length.

Note: these functions are not guaranteed or supported by Please contact the individual developer with any questions or problems.

This is my Custom Function and I want to edit it


There is an error in either this function or fomatN. If I enter formatAmount (123456789; ",") I get the following "?,789.00" returned

Hi David,

The separator in the let had the period and comma in the wrong order. Can you try once more?
By the way, which version of FMP do you use?
