// if the variable current_input1 exists it get the current values 
// otherwise it sets it to 0
var current_input1 = context.get("store_of_current_input1") || 0;
// if the variable current_input2 exists it get the current values 
// otherwise it sets it to 0
var current_input2 = context.get("store_of_current_input2") || 0;

// if the current message is of topic input1
if (msg.topic === "input1"){
    // set the variable current_input1 to the value in the 
    //msg.payload
    current_input1 = parseInt(msg.payload);
    // update the value of  the variable store_of_current_input1 
    //to the value of  current_input1
    context.set(("store_of_current_input1"),current_input1);

}

// if the current message is of topic input2
if (msg.topic === "input2"){
    // set the variable current_input2 to the value in the 
    //msg.payload
    current_input2 = parseInt(msg.payload);
    // update the value of  the variable store_of_current_input2  
    // to the value of  current_input2
    context.set(("store_of_current_input2"),current_input2);

}
  
// check if the condition holds

if (current_input1>10 && current_input2>10 ){
    msg.payload="alto";
}
else{
    msg.payload="basso";
}
return msg;
