    Hi When we close the app the data gets deleted. Do you have any solution for this problem?

    Good morning, my name is Massimo and I'm just a beginner with programming, I wanted to make an application that would allow me to save the number of exercises I do every day to train my leg and arm.
    In practice I would like to make a list where in the first field there is the date, in the second field there is for example arm and in the third field there is the number of repetitions.
    With the inventor app is it possible to create a table where there is each record with three fields or do you need to create three lists with different names?

      You can use the split block to split sentences using . (Full Stop) and then add it to a list variable.
      I showed how to use split block here: th-cam.com/video/0Lxe6hLQ5SU/w-d-xo.html

    • @KrishnaRaghavendran

      You can use For Loop to loop through the list items and find the names.

    Strange, I made this exactly as you did but I get an error saying "bad arguments made ...." when using update or remove
    Edit: nevermind I found the problem, used 'selection' instead of 'SelectionIndex'
