Selecting the Checkboxes on Interactive Report

Question

Hello
I have two checkboxes on a Interactive Report:
My query is as follows:
select
apex_item.checkbox(1, empno, 'ENABLED'),
apex_item.checkbox(2, deptno, 'ENABLED'),
ename,
sal
from emp;
I have a conditional button 'Check N Update' which will invoke the Pl/SQL process:
FOR i in 1..APEX_APPLICATION.G_F01.count
LOOP
l_empno := APEX_APPLICATION.G_F01(i);
UPDATE XXX ....;
END LOOP;
FOR i in 1..APEX_APPLICATION.G_F02.count
LOOP
l_empno := APEX_APPLICATION.G_F02(i);
UPDATE XXX ....;
END LOOP;
What I need is I need to check a CONDITION, if BOTH the checkbox's are selected then I need to throw an ERROR saying.
YOU CANNOT SELECT BOTH the boxes.
Please let me know how can I get this.
Appreciate your help.
thanks

Hi
Using a RadioGroup would actually create one radio button for each line and mean that you could only select one line.
As the submit process will only return the boxes that have been checked, you only have access to the ticked items and as these contain just the EMPNO and DEPTNO values, you have no way to check if any two are from the same row.
This means that you will have to rethink your report slightly. You will need to have two checkboxes with ROWNUM as the value (if the report is sorted somehow, this may make this more awkward as ROWNUM is from the unsorted data) and make your EMPNO and DEPTNO hidden fields. The when the user submits the page, you will have to compare the ROWNUM values for the first column with all the ROWNUM values for the second column to see if there's a match.
As an alternative, you could have a select list for the first item and give the user options for EMPNO, DEPTNO, Both, Neither?
