Hi,
It's hard to say for sure without seeing the whole screen but just on the screen there are several things:
1) The screenshot shows this is inactive. You may have turned it off while testing. Make sure it is active.
2) I would make sure the "isolate script" is unchecked.
3) You may want to try it similar to an existing script to follow what SN does. I found this one on another table that SN is doing something similar for an onChange client script:
var state = g_form.getValue('error_status');
if (state === 'fixed' || state === 'ignored' || state === 'reviewed') {
var fields = g_form.getEditableFields();
for (var x = 0; x < fields.length; x++) {
g_form.setMandatory(fields[x], false);
g_form.setReadOnly(fields[x], true);
}
}
