I need to ask the obvious. Is the click event wrapped inside of a $(document).ready()? If not then the click event will fail on page load.

There is also this.

<input type="checkbox" id="aaaa01" class="classtocheckbox" name="aaaa01" />
<label for="aaaa01">this is a test</label>
<input type="checkbox" id="aaaa02" class="classtocheckbox" name="aaaa02" />
<label for="aaaa01">this is a test 2</label>
<script>
    $(document).on('change','.classtocheckbox',function(event){
        var id = "#AHYSChk"+this.id.slice(-2)
         $(id).toggle();
    }
</script>

>Yeah, there are at least 3 rows being created within a FOR loop and each one has a set of checkbox/radio combinations

>>The on() function creates an event and it doesn't matter if the page is not fully rendered when created. Using bind (which click is a shortcut for bind('click').. ) will fail if the DOM is not fully loaded. That is why you need to have bind events inside of $(document).ready() event.
