Graying out Levels in ACBC holdouts

Dear Forum,

I have included 3 holdouts (with 3 concepts each) in my survey and I'd like to gray out the same levels so it looks more like the other ACBC tasks. Is there a code or function to do so in Sawtooth 9.4?

Place this code in the CBC:

[% Begin Unverified Perl
my $attributes = 4;
my $concepts = 3;

my $out = '';
for (my $a = 1; $a <= $attributes; $a++) {
    my $same = 1;
    for (my $c = 2; $c <= $concepts; $c++) {
        my $this = CBCDESIGNLEVELVALUE(QUESTIONNAME(), $c, $a);
        if ($first != $this) {
            $same = 0;
    if ($same) {
        if ($out ne '') {
            $out .= ',';
        $out .= '#' . QUESTIONNAME() . '_div .cbc_concept > .cbc_cell:nth-child(' . $a . ')';
return $out;
End Unverified %] {
    background-color: lightgray;

Lines 3 and 4 must be updated with the number of attributes and concepts in each task.  Line 26 can be updated with your preferred background color.

That is amazing, thanks! I am sorry to ask again but where exactly can I add the code in the CBC Task. I cannot find the HTML input box.

Thanks in advance,
Anywhere in the task.  I put the code in the footer.
Hi Zachary,
thanks for the quick reply. Unfortunately when I copy paste the code in the footer (or anywhere else) and then preview the page, my laptop gets very noisy and the sawtooth software crashes. Do you know what I am doing wrong?
That is quite abnormal.  What version of SSI Web / Lighthouse Studio are you using?  Is there an error message when the software crashes?
