The rule doesn't return anything; it adds/inserts/injects variables with names "Barcode 1", "Barcode 2", etc. into the variables list. (This is sometimes called "variable injection.")

These added variables can be used just like any others in text frames. They may not actually appear in the Variable drop-down on the Text Editor if you add them this way, but you can always type any variable name you want in there and click Insert. In this case, though, since the names are the same as your fields, you should be able to just insert the variables directly from the drop-down without typing their names first. Also, you probably already have each frame set up to call each variable name like "Barcode 1", "Barcode 2", etc., so you probably don't need to change those frames at all.

That said, if you also have multiple text frames with those same names, you could do this instead:
Code:
for (var i = 1; i <= 18; i++)
{
    var fieldName = "Barcode " + i;
    var data = Field(fieldName);
    var barcode = "";
    if (data)
    {
        data = Right("00000000000" + data, 11); // pad to 11 chars with leading zeros
        barcode = '<span font="IDAutomationUPCEANS">' +
                    TaggedTextFromRaw(MakeUPCABarcode(data)) + '</span>';
    }

    FindTextFrame(fieldName).content = barcode;
}
Here, instead of adding text variables, which can be called out in text frames, you're directly assigning the content of each text frame.

Also, I haven't seen your template, but I suspect that you're simply outputting all these barcodes in some close arrangement on a page, in which case you could probably make a text rule that returns all of the barcodes and whatever other content you want, all together, and just use that single rule in a frame. Or maybe a repeatable component would be a better solution, or even a table. Again, though, without seeing the template, I'm kind of guessing.

P.S. If you're coming to the Print show, I would be happy to do a hands-on with some of this stuff, either at the show itself or at the happy hour.

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.
