    1. COHey, thanks for the answer, `tempballVelocity` is global because I can't get it to work if it's not a global. I changed the second `if` to an `elif` and removed the global but the problem remains. So is what you're saying.. because I'm creating `tempBallVelocity` inside an if statement, it will be deleted once that if statement is completed? If so, do you know how I could work around this? I tried creating `tempBallVelocity` outside of the method and passing it as a parameter, but `_on_keyboard_down` can only take 5 arguments, hence that method won't work. Any ideas?

    2. COYes, the variable is no longer accessible outside of the block. Just try to add `tempBallVelocity = 0` before the first `if`. If you want the variable to be persistent between calls you need to make it an instance variable using `self.tempBallVelocity` and initialize it in the `__init__` function.

    3. COWonderful, the former didn't work, however the latter worked. I appreciate it, Thank you. Now All I need to do is try and get the pause and unpause working by only using one button. I've tried it by doing nesting if statements, but what happens is that the first if statement will execute, and this will enable `paused` = `true`, but the NEXT if statement checks if paused and as such it unpauses it at the exact same time. I've also tried it with a while loop but the same thing happens. Do you think it would be wisest to make a new question or update my existing one?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
