List split-last element


Give a look to block.

if the last imput "compensation" is blank, it gives me the error in which app inventor says that there are only 7 elements in list, and not 8 as i set in "when AddPeople initialize"

i find the solution to add "unknown" if the texbox "compensation" is blank, do you have other solutions?

what about adding your values into a list and pass the list to the other screen?

⦁ How to work with Lists and Lists of lists (pdf) by appinventor.org

also there also exists the mutator functionality for local variables...

actually you do not need local variables at all, just assign the list items directly to the labels...

thanks for reply.
the real problem is that i prefer not use too much the DB in this case, cause i have to delete these lists when i save the contact (wevery contact has many list, "tags, organizations etc)
