Hello, You just did a little mistake : btc_custom_loc is an array so the syntaxe for multiple element in the array looks like this: btc_custom_loc = [town1,town2,town3] so in your well documented problem just do this :   btc_custom_loc = [[[5278,933.486,95.536],"Kampung Bunian","Mountain 1",600,600,true],[[6107.78,6735.1,181.26],"FOB Ayam Emas","Mountain 3",500,500,true],[[545.14,3141.56,175.555],"Kampung Durian Tiga Batang","Mountain 2",500,500,true]]; I hope I didn't do any syntaxe error ;) Have fun !   Also this could be more readable : btc_custom_loc = []; //first create an empty array //Then add each city by pushing then back to btc_custom_loc btc_custom_loc pushback [[5278,933.486,95.536],"Kampung Bunian","Mountain 1",600,600,true]; btc_custom_loc pushback [[6107.78,6735.1,181.26],"FOB Ayam Emas","Mountain 3",500,500,true]; btc_custom_loc pushback [[545.14,3141.56,175.555],"Kampung Durian Tiga Batang","Mountain 2",500,500,true];
