I am sorry I didn't mention it.. you have to use the template editor to add the code.
Where did you added?

In the template editor, print answers table and printanswers.pstpl after {ANSWERSTABLE}


the error appears when I try to save the pstpl file

OK, the JQuery lib is not present for PrintPage.

Try this:
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
var $overview_row = $( "tr.printanswersgroup td:contains('Overview')" ).parent();
$overview_row.nextAll("tr.printanswersquestion").remove();
$overview_row.nextAll("tr.printanswersgroup").remove();
$overview_row.remove();
});
</script>

sorry!!!

same error with this code

Is like a ping timeout trying save this code

Strange, it works good on my end... can you provide a screenshot of the error?

Maybe we can go skype and share screens on monday?

Could it be a problem that my virtual server does not have internet access?
Send me a private message with your skype user to add you as soon as possible

Internet Access! Yes, in the script I grab the latest JQuery Lib from a CDN.
I will write some new code for you to grab it from the FS.

Cheers

Sorry, I just re-read the message.

You are having the error when updating the template...
There must be something else..

Yes, I put the code in the pstpl, click save and nothing happens
I need to reload the page but the changes is not reflected.

Hi
If you want to hide a specific row of a table, you can try a CSS :nth-child pseudo-class approach...
Add this simple code to your template; Adapt if necessary.
Dont' forget to clear your browser cache before testing.

Thanks, finally with this CSS works now
