Adding textbox values together for the total

Hello, I am having trouble with getting the total of the value of the two text fields(labeled price1, price2). If anyone could help me add them that'd be greatly appreciated, thanks :D

 

<script>
function price(sum,val)
{
e =  document.getElementById(sum);

  document.getElementById(val).innerHTML = e.value;

   }  
     
        </script>
Amount: <input type="text" id="price1" value="0" onkeyup="price('price1','price1_price')"> <b>First Price</b>  $<span id="price1_price">0</span><br>
Amount: <input type="text" id="price2" value="0" onkeyup="price('price2','price2_price')"> <b>Second Price</b>  $<span id="price2_price">0</span>
