I have no problems running the code as an HTML page. Now, in a web form, the converter simply does nothing. Was trying to migrate it over to a web form page from HTML to use a master page and theme. 

```
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
 <script lang="javascript" type="text/javascript">
    //Convert Logic
    function CelsiusConvert() {
        document.converter.fahrenheit.value = (document.converter.celsius.value * 9 / 5) + 32
        document.converter.kelvin.value = document.converter.celsius.value * 1 + 273.15
    }
    function FahrenheitConvert() {
        document.converter.celsius.value = (document.converter.fahrenheit.value - 32) * 5 / 9
        document.converter.kelvin.value = ((document.converter.fahrenheit.value - 32) * 5 / 9) + 273.15
    }
    function KelvinConvert() {
        document.converter.celsius.value = document.converter.kelvin.value - 273.15
        document.converter.fahrenheit.value =   ((document.converter.kelvin.value - 273.15) * 9 / 5) + 32
    }
 </script>
</asp:Content>

 <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
   <form name="converter">
       <!--Input Fields-->
       Celsius:
        <input type="text" name="celsius" onchange="CelsiusConvert()"/><br />
       Fahrenheit:
        <input type="text" name="fahrenheit" onchange="FahrenheitConvert()"/><br />
       Kelvin:
        <input type="text" name="kelvin" onchange="KelvinConvert()"/><br />
       <!--Convert Button-->
        <input type="button" value="Convert!" />
   </form>
   </asp:Content>

```
