APEX

I'm using apex 5.1 and universal theme.

I have a page below where the classic report below the chart has a link to URL that has this value

Below is the js, I can see the alert but the focus is never set to the p1_charge_type which is on the 2nd tab screen (pls see below)

function linkDetail() {

alert('testing');

$s('P1\_CHARGE\_TYPE','PT');

apex.item('P1\_CHARGE\_TYPE').setFocus();

}
