Default Multiply result of rounding

I've created this rule which fills my first need. Now I need to take the result of this and multiply by 1.5

if (StringToNumber(Field("GIFTAMNT")) < 20.01)
{
return "<span>" + String("20") + "</span>";
}
if (StringToNumber(Field("GIFTAMNT")) > 500)
{
return "<span>" + String("500") + "</span>";
}
else
{
return "<span>" + (Math.ceil(Field("GIFTAMNT")/5)*5) + "</span>";
}
return "";

{
return "<span>" + (Math.ceil(Field("GIFTAMNT")/5)*5) + "</span>";
}
return "";
All those <span> tags do nothing. I would start by getting rid of them, and then write the rule like so:
Code:
var num = StringToNumber(Field("GIFTAMNT"));
var result = 0;

if (num  < 20.01)
    result = 20;
else if (num > 500)
    result = 500;
else
    result = Math.ceil(num/5)*5;
    
return result * 1.5;
Or, more succinctly:
Code:
return Math.ceil(Math.max(20, Math.min(500, StringToNumber(Field("GIFTAMNT"))))/5)*7.5;

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.

Thanks Dan, This does exactly what I needed.

Curious, if the <span> tag does nothing why does the rule wizard put them in when you convert to javascript?

The Drag-and-Drop Rule Wizard puts in those tags because it *might* be changing the font, or some other style attribute of the text, in which case there will be other formatting tags directly following the <span> tag. But if there are no style changes, it's basically superfluous. I suppose the "Convert to JavaScript" logic could be changed to not bother putting out an empty <span> tag when there's no style change, but that Drag-and-Drop editor was not designed with the goal of producing simple converted JavaScript code. In any case, if you're simply doing a basic "if-else" chain and returning plain text without any formatting tags, I think it's just as easy to write the JavaScript code as to use that Drag-and-Drop GUI, especially if you're already familiar enough with JavaScript to be calling out Math functions.

Thanks for the explanation Dan.

I use the wizard to get some code started, then start editing. Gives me a little head start since I don't get to do more involved scripts all that often.
