How do you use a selected value as input to another function?

You get the selected value with
  var select = document.formName.selectName;
  var value = select.options[select.selectedIndex].value;
Then you pass it into a function 
  functionName(value);
You can do that in the event handler onchange
  <SELECT NAME="selectnName"
          ONCHANGE="var value = this.options[this.selectedIndex].value;
                    functionName(value);"
