Display Moreyou don't need conditional expressions to do this on a gma3
Assuming you have properly set the variable $song as an integer, the following syntax should do the necessary math to achieve the same as your gma2 conditional syntax does
SetUserVar "song" 9
View 200$song /Screen "3"
OK: View 209 /Screen "3"
SetUserVar "song" 10
View 200$song /Screen "3"
OK: View 210 /Screen "3"
Thanks!
