<body>

<div class="container">
<h1>Tips calculator</h1>
<div id="calculator">

<form>
<p>cat a fost nota dre plata?</p>
<input id="billamt" type="text" placeholder="valoarea notei">RON

<p>cum a fost servirea?</p>
<select id="serviceQual">
<option disabled selected value="0"> --alege o optiune</option>
<option value = "0.3">30% superb</option>
<option value ="0.2">20% satisfacator</option>
<option value = "0.15">15%ok</option>
<option value="0.10">10% nemultumit</option>
<option value = "0.05">5% nasol</option>

</select>
</form>

`function calculateTip(){
var billAmt = document.getElementById("billamt").value;
var serviceQual = document.getElementById("serviceQual").value;
var numberOfPerson = document.getElementById("peopleamt").value;



if (billAmt === "" || serviceQual ==0) {
alert("va rugam adaugati o valoare");
return;



}



if(numberOfPerson === "" || numberOfPerson <=1){
numberOfPerson=1;
document.getElementById("each").style.display = "none";
}else{
document.getElementById("each").style.display = "block";
}



var total = (billAmt * serviceQual) / numberOfPerson;
total = Math.round(total * 100)/100;



total = total.toFixed(2);
document.getElementById("totalTip").style.display = "block";
document.getElementById("tip").innerHTML = total;
}



document.getElementById("totalTip").style.display = "none";
document.getElementById("each").style.display = "none";



document.getElementById("calculate").onClick = function(){
