Function calling only the last Javascript API

Question

All,
I have a function in my page header:
function DisableANo(){
//1
$f_DisableOnValue('P20_B','AAAA','P20_A');
//2
$f_DisableOnValue('P20_B','BBBB','P20_A');
//3
$f_DisableOnValue('P20_B','CCCC','P20_A');
I am calling this function on Item B's onChange event.
When I do this, only the last //3 API is being called. If i remove //3 and have only //1 and //2, then I get //2 to work and if I remove //2 and have only //1, then I can get //1 to work.
Can you please tell me where i am going wrong?
Thanks!

Hi,
I am trying to disable the item P20_A if the value of item P20_B is in 'AAAA' or 'BBBB' or 'CCCC'.Review the documentation:

$f_DisableOnValue(pThis, pValue, pThat)
Checks the value (pValue) of an item (pThis). If it matches, this function disables the item or array of items (pThat). If it does not match, then the item is enabled.

So in this code (and code should always be posted using <tt>\...\</tt> tags):
function DisableANo(){
//1
$f_DisableOnValue('P20_B','AAAA','P20_A');
//2
$f_DisableOnValue('P20_B','BBBB','P20_A');
//3
$f_DisableOnValue('P20_B','CCCC','P20_A');
}If <tt>P20_B == 'AAAA'</tt> //1 will disable <tt>P20_A</tt>, then because <tt>P20_B == 'AAAA'</tt>, //2 will enable <tt>P20_A</tt> because <tt>P20_B != 'BBBB'</tt>, and so on etc...
Try <tt>$x_disableItem</tt>:
$x_disableItem('P20_A', (($v('P20_B') === 'AAAA') || ($v('P20_B') === 'BBBB') || ($v('P20_B') === 'CCCC')))
