Hi guys,
I just finished to design what looks like a conference app. Never used no-code tools before, it’s amazing. Thanks for sharing the advanced templates. It helped me a lot.
I’m now struggling with something that has to be simple. Users can fill in a form for every event they plan to attend. As soon as the event’s finished, I’d like to have them give some feedback in a specific tab. I can do the tab and the feedback form.
However I can’t only display the events that users attend. They are all up and running.
I’m pretty sure it’s nothing but damn I’m having a hard time.
Thanks for your help.

So if I get it, you’d like to display just the events that the user has attended ? Is that correct ?

Hi Aymen,
Thanks for pour quick reply. Glad to be on board with u guys.
Yep that’s correct. As soon as they are displayed in a specific tab, I’d like the user to provide some 5-star rating on each. Fortunately I know how to do the last part. But no clue on the first one.
Thanks guys.

Do you need an average of this to display later?

Thanks guys. It helped a lot. 🙂
Any thoughts on how to count the number of items in a “look up” column?
Cheers.

I think you’re asking the wrong question there 😉
When you want to count rows in Glide, the usual way is with a [Rollup Column](https://docs.glideapps.com/all/reference/data-editor/computed-columns/rollup).
Rollups can be applied to entire columns, or to a subset of rows within a column via a relation.
