Instead, on the outputs tab, put in code like &quot;append(pv!responseArray, ac!thisResponse)&quot; --&gt; saving into pv!responseArray. I&#39;d suggest to structure it like this instead of using the hardcoded &quot;append values&quot; from the dropdown, since this way if you decide you need to save different things under different circumstances (i.e. don&#39;t append to the array if the user clicks &quot;cancel&quot; or something), you would only need to wrap the above logic in further if() conditionals to make that work well.<div style="clear:both;"></div>
