I apologize for being so vague in the original post. I didn't want to make it long, considering how simple it seems.

I should have explained that $shown doesn't need to change; it's the number of products that we will appear to have, and if it's zero, then the amount we have will show as a default. I should've explained that.

However, I do think I'm going to be able to get this put together, so thank you all again for your time. :)
