Then I guess it is as if the Javascript wasn't there at all.

Hi,

I intentionally set the group name for not to be shown.

In fact, both the group name and description were hidden.

I just allowed the description to be visible and voila!!!

Thanks a lot to be the saviour.

You all have been helping.

Best regards

Which is perfectly fine.

But then you can't put your Javascript in the group description, because it won't work. Put it into the first question of each group and you should be fine.
