Thanks so much for your reply Kevin. It was great to see how to get a variable out of an if statement. To make it work for my situation I just changed it to the following….
n = thisComp.layer(“Controllers”).effect(“Body Turn”)(“Slider”);
if (n >= 0) j = 1 else j = -1;
m= n*j;
[value [0]+m, value[1]]
Works perfectly, Thanks Kevin!
