I'm working on a script that allows players to scroll a map on a landing page for a campaign. However, I discovered that a user could still scroll the map around even when not on the page. I wanted to make a check at the start of the code that verifies if they player inputting the command request is viewing the page with the map.  A short little example of what the script does:  <a href="https://imgur.com/W2dl0Vq" rel="nofollow">https://imgur.com/W2dl0Vq</a>       function doMapMove(token, orientation, distance){
	try {
	    log(orientation + " " + distance);
        token.set(orientation, token.get(orientation) + distance);
    } catch(err) {
        log("movemap command detected but failed");
        return;
    }
}
on("ready", function() {
    on("chat:message", function(msg) {
	
		try {
            var mapObject = findObjs({_type: "graphic", name: "movable_map"})[0];
        } catch(err) {
            log("No movable_map object detected");
            return;
        }
		
		map_pageID = mapObject.get('pageID');
		
		 player_pageID = ... 
		
			if (map_pageID == player_pageID)
			{
				if(msg.type == "api" && msg.content == "!movemap-up") {
					var distance = 250;
					var move_orientation = "top";
					doMapMove(mapObject, move_orientation, distance);
				}
				
				if(msg.type == "api" && msg.content == "!movemap-down") {
					var distance = -250;
					var move_orientation = "top";
					doMapMove(mapObject, move_orientation, distance);
				}
				
				if(msg.type == "api" && msg.content == "!movemap-left") {
					var distance = 250;
					var move_orientation = "left";
					doMapMove(mapObject, move_orientation, distance);
				}
				
				if(msg.type == "api" && msg.content == "!movemap-right") {
					var distance = -250;
					var move_orientation = "left";
					doMapMove(mapObject, move_orientation, distance);
				}
			}
      });
 });  I know that    playerspecificpages    grabs a list of players and what pages they're on, but how do I get a hold of the player ID of the person entering the command to be able to search that list for a match?
