Custom CBC under SSI Web 7 (Free Format): Autosum Prices of Selected Options & Question Toggle

Dear Forum Users,

I am using custom CBC (free format) under SSI Web 7 to allow for multiple choices in an ordninary CBC. There are three choices and a none option. Using JavaScript I would like to do the following:

1. Toggle 3 product options off, when None is clicked. Here is my according code:

<script type="text/javascript">

var toggle_list = ['fftRandom1_response_1', 'fftRandom1_response_2', 'fftRandom1_response_3'];

function toggle(checkbox) {
if (checkbox.disabled) {
} else {
checkbox.setAttribute('disabled', true);

function toggleActivation() {
for (var i=0; i<toggle_list.length; i++) {
var id = toggle_list[i];
var checkbox = document.getElementById(id);


2. Autosum the prices of selected options to arrive at a total price. Here is my script:

<script type="text/javascript">

function UpdateCost() {
var sum = 0;
var gn, elem;
for (i=1; i<4; i++) {
gn = 'fftRandom1_response_'+i;
elem = document.getElementById(gn);
if (elem.checked == true) { sum += Number(elem.value); }
document.getElementById('totalcost' ).value = sum.toFixed(2);


Here are the according code for the checkboxes:

<td class="input_cell clickable alt_color1" width="22%" nowrap >
<input name="fftRandom1_response_1" value="[%CBCDesignLevelText (CBC01_random1,1,3)%]" type="checkbox" id="fftRandom1_response_1" class="HideElement" onclick="UpdateCost()">
<div id="fftRandom1_response_1_graphical" class="graphical_select checkbox"></div></td>

<td class="input_cell clickable alt_color2" width="22%" nowrap >
<input name="fftRandom1_response_2" value="[%CBCDesignLevelText (CBC01_random1,2,3)%]" type="checkbox" id="fftRandom1_response_2" class="HideElement" onclick="UpdateCost()">
<div id="fftRandom1_response_2_graphical" class="graphical_select checkbox"></div></td>

<td class="input_cell clickable alt_color1" width="22%" nowrap >
<input name="fftRandom1_response_3" value="[%CBCDesignLevelText (CBC01_random1,3,3)%]" type="checkbox" id="fftRandom1_response_3" class="HideElement" onclick="UpdateCost()">
<div id="fftRandom1_response_3_graphical" class="graphical_select checkbox"></div></td>

<td class="input_cell clickable alt_color2" width="22%" nowrap >
<input name="fftRandom1_response_4" value="1" type="checkbox" id="fftRandom1_response_4" class="HideElement" onchange="toggleActivation()">
<div id="fftRandom1_response_4_graphical" class="graphical_select checkbox"></div></td>

Both scripts work fine, if executed under HTML (normal website). However, if I use them under Sawtooth 7 they do not execute. Do you have any suggestions how to fix this problem?

Thank you very much for your help.

All the best,

can you give it a try by turning off the graphical checkboxes in study options? if it works then, it means this is related to the recent graphical checkboxes.

if this is the case, take a look at https://sawtoothsoftware.com/forum/501/graphical-chekbox to borrow some code from there :)
