How can I only show a table row based on the the value of the attached select menu being 1. i.e. So if the value is not 1 it should hide the table row?

Select menu code attached.
<select name="ink_brand_id" id="ink_brand_id">
        <?php
do {  
?>
        <option value="<?php echo $row_rs_ink_brand['id']?>"><?php echo $row_rs_ink_brand['ink_brand']?></option>
        <?php
} while ($row_rs_ink_brand = mysql_fetch_assoc($rs_ink_brand));
  $rows = mysql_num_rows($rs_ink_brand);
  if($rows > 0) {
      mysql_data_seek($rs_ink_brand, 0);
        $row_rs_ink_brand = mysql_fetch_assoc($rs_ink_brand);
  }
?>
      </select>

You can use jQuery to do this.

Assuming the table row to show/hide <tr> has an id='row1'. Add an onchange hander to your <select> element as:

<select name="ink_brand_id" id="ink_brand_id" onchange="showhiderow(this)">

then define the JS function showhiderow() as:
function showhiderow(sel)
{
 var disp = sel.options[sel.selectedIndex].value=='1'?'':'none';
 document.getElementById('row1').style.display = disp;
}
