How to update saved text


Hi guys in need for some urgent help, im a beginner with AppInventor2. Ive so far created an app that will allow me to record audio, save it and display it in a list. The problem comes to when i try to annotate it. For the annotations ive created a textbox which saves the files onto my phone but the issus is that it continuesly saves i.e. adds onto what i previously saved instead of individual saved textfiles. Help Please....

This may require two lists -- one for the recordings, and one for the annotations.
Both lists will share a common index.
So if you are listening to the 3rd recording from the recordings list you should be displaying the 3rd annotation from the annotations list.
Also if you record a new item, it's annotation would be saved at the same time in the annotations list.

You can also append to the list for every download, here are some blocks about appending to the text file on a click, should be pretty close to the same I imagine.  You can even download the app in the Gallery here, it's HERE!  Hope this helps!
Also a good video on YouTube HERE!
