I have a table that is filled in with values dependant on a previous page
those avlues are filled in with struts apparently

but I’m not very good with all that stuff so is there a simple was I can do something like this, either with HTML only or maybe a small javascript I can put in tha page?

<Table>
<TR>
<TH>ID</TH>
<TD><s:property value="groupID" /><TD> <--Number generated by the page with struts
</TR>
<TR>
<TH>ID Value</TH>
<TD>foobar</TD> <-- the text I want to add in dependant on the number from the previous TD
</TH>
</Table>

so, is there a simple way to go about doing this? HTML, CSS, JavaScript solution maybe?

    Given that exact HTML, a simple script like this will do it. But if you don’t know JavaScript, you should really learn it so that you understand what you’re doing.

    <body>
    <Table>
        <TR>
            <TH>ID</TH>
            <TD><s:property value="groupID" /><TD>
        </TR>
        <TR>
            <TH>ID Value</TH>
            <TD>foobar</TD>
        </TR>
    </Table>
       <!-- The script is here so it won't run until the TABLE has loaded -->
    <script type="text/javascript">

          // This is a map of the struts values to your values
        var valueMap = {
            "1": "foo",
            "2": "bar",
            "3": "baz"
        };
          // Browser compatibility. Older IE uses 'innerText' instead of 'textContent'
        var textContent = ('textContent' in document) ? 'textContent' : 'innerText';

          // Get all the TD elements on the page
        var tds = document.getElementsByTagName('td');

          // Get the text content of the first TD (index 0)
        var text = tds[0][textContent];

          // Get the value from the map using the text we fetched above
        var value = valueMap[text];

          // Set the text content of the second TD (index 1) to the mapped value
        tds[1][textContent] = value;
    </script>
</body>
