It looks like this is another try to upload a file to your server
I moved your 2 posts into the correct thread
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...
Also please explain what exactly happens and what you want to happen instead. In case there is an error message, provide the error number as well as the error text, also providing a screenshot could help.
Be as specific as possible. Take as much effort to describe your issue as you want others to provide a useful answer.
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.
