Default Opposite expression help

I need the code below to state the opposite as it is currently. If the field does not contain the value "Commercial," then return value.

Code:
if (Field("version").indexOf(String("Commercial")) > -1)
{
   return "<span>" + Rule("Day of the Week") + "</span>";
}

return "";
Thanks!

The simplest way to turn an if/else statement (which is basically what this is, although you're using a return statement to imply the "else") into its "opposite" is to simply swap the "if" and "else" blocks, like so:
Code:
if (Field("version").indexOf("Commercial") > -1)
  return "";
//else
return "<span>" + Rule("Day of the Week") + "</span>";
Or, you can change the logic in the comparison thusly:
Code:
if (Field("version").indexOf("Commercial") == -1)
  return "<span>" + Rule("Day of the Week") + "</span>";
//else
return "";

I am a not a Support engineer, and this forum is not a substitute for Support. My participation on this forum is primarily as a fellow user (and a forum moderator). I am happy to provide help and answers to questions when I can; however, there is no guarantee that I, or anyone else on this forum, will be able to answer all questions or fix any problems. If I ask for files to clarify an issue, I might not be able to look at them personally.

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.

return "KbwbTdsjqu!spdlt\"".replace(/./g,function(w){return String.fromCharCode(w.charCodeAt()-1)});
