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

This takes any string of digits, with any number of decimal places and an optional negative sign at the beginning, and returns them as a text string formatted dollar sign, commas every three decimal places before the decimal point, and two decimal places after the point.

The advantage of the recursive method used is that there is no maximum limit on the length of the number which is to be converted.

There appears to be an error in the formula in the line: 'If(Digits<0;"-";"")&"$"&'

If you replace 'Digits' with 'Number' (the correct parameter), it works.
