Correct, the alert does not pop-up. I am using IE, and already did as you described when I first set the variable. It is "Plans selected values" as its title.
As I mentioned, I changed the if statement from;
if (selectedValueDisplay !== null) {
to
if (1 === 1) {for testing purposes. When I did this, the if statement results as true, and the alert pop-ups saying "SelectedValueDisplay is not null", but the multi select still does not update like it should after the rest of the code is ran.
