    Hi guys, I’m having some issues with a code.

    I set up a code that controls font size and leading size with 2 sliders.
    The problem that it works only on one of them. If I place the font size at the bottom it’s the one that works. And if I put the leading one at the bottom it’s the one that works. Please help!

    var x = effect(“font-size”)(“Slider”).value;

    var y = effect(“line-space”)(“Slider”).value;

    if ( x == 2) {style.setFontSize(50)}else {style.setFontSize(100)};

    if ( y == 1) {style.setLeading(100)}else {style.setLeading(50)};

    Looks like the styles need to be on the same line. Try this:

    var x = effect("font-size")("Slider").value;

    var y = effect("line-space")("Slider").value;

    var myfontsize = 50;

    var myleading = 100;

    if ( x != 2 ) {

    myfontsize = 100;

    }

    if ( y != 1 ) {

    myleading = 50;

    }

    style.setFontSize(myfontsize).setLeading(myleading);
