Dynamic toggle with php

The toggle here is not working...

<p><?php
                  $result = mysqli_query($con,"SELECT * FROM table WHERE qid=".$qid." ORDER BY RAND()");
                  while($row = mysqli_fetch_array($result)) {
                        if ($row['otxm']!=NULL){
                        echo "<span class='radioitem'>";
                        echo "<input type='radio' name='q".$_SESSION["nextPage"]."' value='".$row['scaleValue']."' onclick='toggleDisplay('toggle".$row['scaleValue']."');'>";
                        echo $row['scaleText']."<span id='toggle".$row['scaleValue']."' style='display:none;'>".$row['otxm']."<input type='text' name='otext".$row['scaleValue']."' /></span></span><br>";
                        }
                        else {
                        echo "<span class='radioitem'><input type='radio' name='q".$_SESSION["nextPage"]."' value='".$row['scaleValue']."'>".$row['scaleText']."</span><br>";
                        }
                  }
                  ?></p>
                  
                  
<script type="text/javascript">
<!--
    function toggleDisplay(id) {
            document.getElementById(id).style.visibility = "visible";
            if(document.getElementById(id).style.display == "none" ) {
                  document.getElementById(id).style.display = "";
            }
            else {
                  document.getElementById(id).style.display = "none";
            }
      }
//-->
</script>

I guess the problem is in onclick='toggleDisplay('toggle".$row['scaleValue']."');'
combining all these single/double  quotation marks.
Any Ideas?

Yeah the single quote is cutting your function call short... try changing your radio element to escape the quotes around the string paramater in your onclick call like this:

echo "<input type='radio' name='q".$_SESSION["nextPage"]."' value='".$row['scaleValue']."' onclick='toggleDisplay(\"toggle".$row['scaleValue']."\");'>";
