My code is currently set up to grab the data from the last row in a table. How can I change it to only grab the second row?

```
<script>
$(document).on('globalUpdate', function() {

 $ (".diff").each( function(){
var curr = parseFloat($ 
   this).closest("tr").find("td:last").find(".vertical").text())
var target = parseFloat($ (this).closest("td").find("b:first").text())
if ((target-curr) > 2.0 || (target-curr) < -2.0){
    if ((target-curr) > 3.0 || (target-curr) < -3.0){
        if ((target-curr) < -3.0){
            if ((target-curr) < -6.0){
                $ (this).html("<span style='padding-left: 19px; color:#f02;'>" + String((curr-target).toFixed(2)) +"% <span style='font-size: 15px; color: #A33315; float:right;'>&#9940;</span></span>")
            }
            else {
                $ (this).html("<span style='padding-left: 19px; color:#d50;'>" + String((curr-target).toFixed(2)) +"% <span style='font-size: 15px; color: #A33315; float:right;'>&#9940;</span></span>")
            }
        }
        if ((target-curr) > 3.0){
           if ((target-curr) > 6.0){
                $ (this).html("<span style='padding-left: 19px; color:#f02;'>" + String((curr-target).toFixed(2)) +"% <span style='font-size: 19px; color: #005EA5;font-weight:900; float:right;'>&#8679;</span></span>")
            }
            else {
                $ (this).html("<span style='padding-left: 19px; color:#d50;'>" + String((curr-target).toFixed(2)) +"% <span style='font-size: 19px; color: #005EA5;font-weight:900; float:right;'>&#8679;</span></span>")
            }
        }
    }
    else {
        $ (this).html("<span style='color:#980'>" + String((curr-target).toFixed(2)) +"%</span>")
    }
}
else {
    $ (this).html("<span style='color:#060'>" + String((curr- 
target).toFixed(2)) +"%</span>")
}
});

})
function legendVis() {
document.getElementById("legend").style.opacity = ".9";
}
function legendTrans() {
document.getElementById("legend").style.opacity = ".5";
}

function tHs() {
var right = document.getElementsByClassName("table-hdr-cell");
right.getElementsByTagName("span").innnerHTML = "Current";
}

</script>

```

I believe the change needs to occur with the:
 find("td:last")

I've tried changing the last to second, 2nd, and next but it doesn't work that way.
