window.οnlοad=function(){
        		var count=1;
                 var count1=1;
        		var adult=document.getElementById("btn1");
                var adcount=document.getElementById("btn2");
                var adco=document.getElementById("btn3");
    
                var child=document.getElementById("btn4");
        		var chcount=document.getElementById("btn5");
                var chco=document.getElementById("btn6");
    
                    adult.οnclick=function(){
                       
                    count++;
                    adcount.innerHTML=count;
                      adco.οnclick=function(){
                    if(count>0){
                       count--;
                    adcount.innerHTML=count; 
                }else{
                    adcount.innerHTML=0;
                }
           }
                   
        }  
       
            child.οnclick=function(){
                    count1++;
                    chcount.innerHTML=count1;
                chco.οnclick=function(){
                    if(count1>0){
                    count1--;
                    chcount.innerHTML=count1;  
                    }else{
                    chcount.innerHTML=0;
                    }
                }         
                    
            }
        }
