Need help with Javascript to get value of standard report column

Question

Hello All,
Apex version 3.1
I have a SQL Query (Updateable report) region where I need to do some validations using an OnDemand Applicaiton Process and javascript. For this validation I need to use the serial number and the item id from the same report row. The function is called when the serial number is changed. I can get the serial number easily because it is a Text field, however the item id is a standard report column (making it a text field or hidden gives me a checksum error, long story). How do I get the value for the standard report column in order to set the value for an Application item to be used in my Application Process along with the serial number? Here is my code below.
<script>
function f_ValidateSerial(pThis)
  // The row in the table
  var vRow = pThis.id.substr(pThis.id.indexOf('_')+1);
    //alert('Row is '+vRow);
  // Display the serial number
    //alert('The Serial Number is '+html_GetElement('f21_'+vRow).value);
var get = new htmldb_Get(null,&APP_ID.,'APPLICATION_PROCESS=ValidateSerial',0);
get.add('F101_SERIAL_NUMBER',html_GetElement('f21_'+vRow).value);
get.add('F101_INVENTORY_ITEM_ID',+html_GetElement(?????+vRow).value);   // Here's where I need to get the item id to set application item!!
gReturn = get.get();
if (gReturn)
      alert(gReturn);
  if(gReturn)
      html_GetElement('f21_'+vRow).value = '';
</script>

Hi,
Ok, No standard report column do not have name attribute-
You can add one extra column to report that is your Item Id with different alias.
Then change that column Display as to "Hidden".
Now you have hidden input where is your Item Id. Than input have name and id.

JariBut this puts me back to my initial problem. When making the column hidden I get the checksum error...
Error in mru internal routine: ORA-20001: Error in MRU: row= 0, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process...
The item id is NOT in the table which I am updating (I use a subquery to get the data) so I think it has to be a standard report column. Hidden and Text Item (which have an item id) all generate the checksum error.
So I think I'm back to my original question. Given a standard report column on a row in a sql query (updateable report) region how do I get the value using Javascript?
