I need your help.

Also, I have no intention of making money from this application I’ve created.I just enjoy creating applications and writing code. I will share the aia file at the end of this project.Since this is a community forum, I’m asking for your help. I would appreciate your assistance.

Nothing has changed, I’m still getting the same error.

Tell me when did you get the error. At what stage.

When you created the 1st dynamic component, did you check whether it got created or not. Got any errors at that time…?

Thanks for your comment, I solved the problem. It turns out the issue was caused by the - block I was using in the IF and ID blocks.I deleted and rearranged them, and the problem was solved.
Thank you for taking the time to help. :heart:
Another problem I’m currently experiencing is that there are three movies in one row in the movie list. When I click on one movie, the remaining two Cardviews are also clicked.And when I click on the movie I want, the player (web viewer) doesn’t open.

So how do you feel…? solving the problem by yourself…!

Show me the how you did it…

I’m sorry, I didn’t understand what you said. What exactly do I need to do to make the movie open when I click on a photo?

8

On the 7th block, add a key value pair = Full Clickable to true.

Thank you, the problem is solved. However, the video doesn’t open when I click on it. Why?

10

Check for the Result, what you are getting when you click…

Change them and tell me what happened…

13

I think you misunderstood me. I want the video to open when I click on a movie in the movie list. It was working before I added Cardview, but it doesn’t work now.

14

Did you add this…? If you have added, then you just have to replace this block (when any Image.click) to (when any Card View Click.)

It’s better to use any Card, rather than any Image.

15

I added the block you mentioned and replaced Image Click with Cardview Click, but when I click on the movie, there’s no response; it doesn’t open.

16

check the output of the clicked component… Can you upload the blocks. but before downloading, download it as a png by right clicking it..

As per you block it seems your video url present in the firebase has the main tag as that of the dynaminc ard id.

Did you set the video url as the key value for the same as the dynamic card id in firebase? are you number as tag in firebase? do not set single digit number as the fb tag.

to debug what are you getting while on the image clic use one lable to catch insted of call web viewer go to url , use one lable set text and you make sure you are geting the video url else correct it. may be video url is in the list. so using this card id as index use, select list item from tehlist index method

I told this thing :index_pointing_up: to do… You didn’t…!
Atleast can you do this…? :backhand_index_pointing_down:

Do as he sugested, both are same, but in a different way.

Hello, there’s no problem with the video link, I checked it and it was working before I added the Dynamic Cardview. Now it’s not working, but I still haven’t figured out why. Could you please
In Firebase, it goes movie1, movie2, movie3, and so on. That’s how I do it; it worked before.
