Default Re: Storing User-Defined Functions

This functionality does work, but you have to use valid JavaScript syntax. In this case, you do indeed have an illegal character.

When I copy that code into a .js file and put it in my plug-ins folder, it says the error is on line 4. The illegal characters are the curly double quotes. They're also on lines 6 and 7. These were probably put in by whatever application you were using to type in the code. (You probably want to use an actual code editing app like Xcode or Sublime Text instead of something that wants to format curly quotes like TextEdit.) You also don't want those the backslash escapes for the double-quotes.

Changing those to straight double-quotes and removing the backslashes, and removing the unnecessary string parameter from your function, this works for me:
Presets = new Object;
Presets.LBLNUM = function()
    return Int(Field("LBLNMBR"));
Presets.LBLNUM.description = "Remove Leading Zeroes from Label Number";
Presets.LBLNUM.syntax = "Presets.LBLNUM()";
I also changed the syntax to include the object name, which is needed to call it.

How To Ask Questions The Smart Way

The correct spellings are JavaScript, FusionPro, and MarcomCentral (each with two capital letters and no spaces). Acceptable abbreviations are JS, FP, and MC (or MCC). There is no "S" at the end of "Expression" or "Printable"! The name of the product is FusionPro, not "Fusion". "Java" is not is not the same as JavaScript.

Check out the JavaScript Guide and JavaScript Reference! FusionPro 8.0 and newer use JavaScript 1.7. Older versions use JavaScript 1.5.
