How do you make the following skip the first field?
<%for each x in rs.Fields%>

set a boolean outside the foreach loop to false and too true after the first iteration: in C# it would be...

bool skipped = false;
foreach (item in rs.items)
{
    if (skipped)
    {
        //do your processing here
    }
    else skipped = true;
}

That is the simple solution.
