Hi guys! Considering that i'm trying to develop the app by using the virtual screen i need to modify the code of the sidebar, that now don't have to go to a screen but to a vertical arrangement. What command i can use to do this instead "open another screen screenName->HOME?"
Thank you! 
Instead of change of screen, hides the "screen" elements you leave and shows the "screen" elements you "open".
If the elements of each "screen" are all in an arrangement it makes it easier to hide/show these "screens". Then only have to hide/show that arrangement instead of each element.
Thank you ramon. I have understood what you say but i don't know how to apply this changes. Can you explain it easier for a newbie? (lol)
Thank you.
You have to set visible property to true or false, depending on if you want to show or hide the elemets. But it is easier if you have only to set an arrangement (which contains all the elements: labels, buttons..) instead of each element.
So, you can place an arrangement, move inside all the elements belonging to the same "screen" and then you have only to set visible property of that arrangement to hide/show that virtual screen.
Hi Ramon, thanks to you i'm almost arrived to the result. If you know there is a way to set more than 5 buttons in the sidebar? i've read that also other users had the same problem. Or do you know if there is another service available for free?
Thank you so much, here is a very beautiful community!
Of course. Use the following block to handle all your sidebar items using their ItemNo.

Hi Timai ! I'm trying to following your instructions until the day you gave it to me but i am not able to do what you told to me. There is another easiest way, considering
the ways in which I am developing my app? I think that the structure of your demo is totally different than mine or i don't know how to adapt it to my app.
Hope you can help me again.
I attack my aia test to show you what happens.

Thank you.
No, we have the same structure, it is just how you use it.
Why not try like this:
You could make use of lists and a bit of logic to further simplify the event block.
hello
Select list item: Attempt to get item number 1 of a list of length 0:
how i can solve this problem in this aia??? please help me
Please show your relevant blocks
ok just a second because i really really need your help
its the same aia but with another xml url
and another question , can i use rss feed url without ending with .xml?? (i mean from blogger)
Can you please let me know if you can help me?
I guess you should be patient. Power Users are volunteering their free time to help others.
Thanks
Because I did not find any solution for this problem and how to display the rss feed in any other platform
What is the problem with this other xml url in this same aia project ?
You may need to show an example of what you are attempting ?
when click on button..show error select list item
Go on...
Show what it is you are doing, blocks, data etc.
If you are asking for help, I recommend you to make it as easy for others to be able to help you ...
You probably will get more feedback then...
which means in your case post a screenshot of your relevant blocks...
To download the aia file, upload it to App Inventor, open it, do some bug hunting for you, etc... this takes time, and most people will not do that...
Thank you.
