I’m not sure you’ve got all of the logic you need in there. Go through each of the bullets in the instructions one at a time (ignore the first one) and create an if statement for each one and do the required task inside each if statement. Don’t try to get tricky with logic, just brute force it. Get it working first.

Since there are four bullets, you should have four if/else-if statements.
