    Hey guys,

    I want to add a plus symbol in front of the increasing percentage number but I’m not having any luck. Here is the This expression is working great for the percentage attached to a slider:

    math.round(this.Comp.layer(“Slider”).effect(“Slider Control”)(“Slider”))+”%”

    Any ideas? Thanks.

    math.round(this.Comp.layer(“Slider”).effect(“Slider Control”)(“Slider”))+”%”

    Like this?

    “+”+Math.round(thisComp.layer(“Slider”).effect(“Slider Control”)(“Slider”))+”%”

    Thanks for the reply, Dan, that was my guess as well. I will try it again unless I missed something but I don’t think it worked. Any other thoughts?

    >I don’t think it worked

    Please explain. Did it not do what you wanted? Did you get an error message?

    Well now I feel a little silly. The last time I tried it I must have broke something else in the expressions accidentally because I tried again and it works! Problem solved thanks for the help.

    Hi Dan & CC community,
    so, I’m reviving a 5-year-old thread – registering a new account in the process – because I have a similar problem. I’m using a slider to display a number on a text layer. It’s for an election graphic where I want to display the results of the previous and current election. Everything works smoothly, except that I want it to show a plus sign, if the party has more votes than before and a “+/- 0” if it stayed exactly the same. The minus works by itself if the result is negative, but I can’t seem to figure out the rest on my own… Any help is very much appreciated.

    It’s not clear (to me at least) what you’re asking. What are you comparing against? Also, I don’t understand the “+/- 0” part at all.

    I’m comparing the current election results against the previous one showing the changes with a number. While the maths automatically shows a minus in front of a loss of votes, I’d like to show a plus in front of a positive change. If nothing changed at all, I want it to literally show “+/- 0” (Instead of just 0).

    Something like this then:

    current = Math.round(effect("Current")("Slider"));

    prev = Math.round(effect("Previous")("Slider"));

    diff = current - prev;

    if (diff < 0){

    prefix = "-";

    }else if (diff > 0){

    prefix = "+";


    prefix = "+/-";


    prefix + Math.abs(diff)

    The icon has struck again! You are the absolute best! Next to no adaptations and it fit my project and need perfectly! Your code even allowed me to figure out something else I couldn’t wrap my head around previously – THANK YOU SO MUCH, DAN!
