APEX

Hi friends,

i have two select list page item(in which both the items has a static lov's---> 'Y', 'N')

Suppose, if i select the combination like the below

P1_select--->N
P2_select--->N

Soon after that i need to raise an error like *'this combination cannot be allowed'*

For that i tried with the Dynamic Actions like the below

EVENT: CHANGE

SELECTION TYPE(S): ITEM

ITEM: P1_SELECT,P2_SELECT

Condition: No Condition

Action: Execute Javascript Code

Code:

sel1 = $v('P1_SELECT');
sel2 = $v('P2_SELECT');
if  (   (sel1 == 'N' ) &&  
        (sel2 == 'N')
     )
     {
       throw "Err1";
}
catch(er)
  {
  if(er=="Err1")
    {
    alert("Error! The Combination is not possible");
    }

But it is not working, as it is not raising any error soon after giving 'N' and 'N' in both the page items. Can anyone help me with this friends.

Brgds,
Mini
