Referencing Report Fields from other regions

Question

It is possible to reference the value in a report column in another part of the page?
I have a report region returning a single row of data, and I'd like to use the value in one of these columns to set an item in another region.
Is there any way to reference the report column directly from another region, or do I have to do something more complicated?

Hi,
OK - it would depend on the template that is being used. See: [http://apex.oracle.com/pls/otn/f?p=267:80]
In this case, I have added the following into the report region's Region Footer setting:
<script type="text/javascript">
var region = document.getElementById('#REGION_ID#');
var t = region.getElementsByTagName('TABLE')[1];
</script>Underneath this region, I have another region containing a P80_VALUE page item. To populate this with the first EMPNO shown in the report, I have added the following into this region's Region Footer:
<script type="text/javascript">
function showValue()
var r = t.rows;
var row1 = r[1];
var c = row1.cells;
var v = c[0];
document.getElementById('P80_VALUE').value = v.innerHTML;
showValue();
</script>In this example's case, the report region actually generates two tables with the same ID (this is defined on the template, which I have not changed) - so, the first script gets a reference to the second table (items in javascript being zero-based, this is item 1). The script in the second region, then gets the second row (the first one containing data, the headers being on the first row) and then gets a reference to the first cell in that row. Finally, it sets the value of the P80_VALUE item to the contents of the cell. If required, you could loop through the rows and cells using something like:
for (var row = 0; row < r.length; row++)
c = r[row].cells;
for (var cell = 0; c < c.length; cell++)
  do something with c[cell];
