Trying to get the button to show up

Processing Libraries
1

** I have this code below and I am trying to get the button to show up but it wont run. I’m getting an error that says expecting EOF, found “last_sum”. I’m not sure how to fix this. The error is talking about this line: last_sum = sum; . Any suggestions on how to fix this? Thanks.

Hi,

You have one too many closing curly bracket :slight_smile:

I need to delete the last one correct? Or would you recommending deleting one on a specific line?

In processing, hit ctrl+t to properly indent all your code. Then just check what are the sections that you want and remove the curly bracket that does not belong to any of them. In you case, processing even underline in red the bad one.
