Volume control using Macrodroid

My friend has the same problem on his Samsung device as described here https://android.stackexchange.com/q/123150/131553 I showed him the solution and it worked beautifully for him. But he would like to make it work whether Google Play Music is in foreground or background, which beeshyams in his answer said is possible but perhaps didn't add as OP didn't ask for that. I have Macrodroid installed ( learner ) and tried to modify that macro by the condition While Google Play Music in foreground OR ( ) Background and it didn't work What am I doing wrong and how to achieve the Macro perform as required ?
