[Sussex] Make IE 7 crash

[Brendan Whelan]

Here is the (untested) code anyway:

<input type="hidden" name="add_file_num" value="0">

<button onclick="doSubmitAddNum(999);" class="formButton" 
name="add_image_1_button">Add image</button>

<script language ="javascript" type="text/javascript">
function doSubmitAddNum(num)
  {
alert('In doSubmitAddNum');
document.form1.add_file_num.value=num;
document.form1.submit();
  }
</script>

Always ensure the field (add_file_num in this case) is defined as a 
hidden input. I left the alert in the code as I have found it very 
useful. If the alert message appears but the form doesn't get submitted 
then the chances are that the "hidden" value isn't defined.
