So basically I was trying to make a savings goal tracker for my school project. I was following a tutorial (can't find it now for some reason), and when I connected it to my phone, quite a bit of errors happened?
you are trying to perform DAYS minus DATE. you should convert start_date to DAYS also using call clock1 with pattern "D" to make them the same units
it looks like you're trying to get the number of dates between 2 dates. this is the proper block to use then. you supply starting and ending date and you get days.
regarding the error you get when you click update_status, it calls 'calculate_status' and that procedure is doing invalid math - see my reply to your earlier post.
for the reset button error, you are getting them because you are setting text fields to numeric eg. set currentvalue.text to 0
change it to set currenttvalue.text to "0"
there are several of them
