What are you trying to do? What is it doing instead? Are you getting an error message?

Did you mean to paste your code twice? Are there differences between the two sketches?

There are a couple of errors with your for() loop:

  1. Variables in p5 are declared with ‘var’ not ‘int’

  2. The expressions in the for() statement should be separated with ‘;’ not ‘,’ and there should not be a terminating ‘;’
