Dynamically calculating values and validating in reports

Question

Hi
I need to be able to calculate and display the running total of column (representing a % - sales allocation) within an updatable report as the users steps off the row after making a change to the allocation.
Greatful for your suggestions on ways of doing this.
Thanks
Dorian

See
http://htmldb.oracle.com/pls/otn/f?p=24317:57
The region query is
select
ename,
job,
htmldb_item.text(1,sal,null,null,'onChange="Calc()"') sal,
htmldb_item.text(2,comm,null,null,'onChange="Calc()"') comm,
htmldb_item.text(3,sal+comm,null,null,'readonly=true') total
from emp
The Calc javascript function is in the Region header as
<script type="text/javascript">
function Calc() {
var sal=document.wwv_flow.f01;
var comm=document.wwv_flow.f02;
var total=document.wwv_flow.f03;
for (var j=0;j<sal.length;j++) {
   total[j].value=Number(sal[j].value)+Number(comm[j].value);
</script>Note that you dont have access to each individual row, when you change either the sal or the comm field, the entire grid gets recalculated, sort of like a spreadsheet.
Should be enough to get you started.
Hope this helps.
