I'm hosting tounaments throughout the year, and have the price increasing each day. Code works, but I'mnot cure which elements to adjust to be able to display multiple prices adjusting simultaneously. I tried changing "rate" to "rate1" etc, but that wasn't enough... So I'm guessing variables within should be adjusted as well. Any help is appreciated. The page I'm working on is here: http://limitlesshoops.com/jamball.html -- The sinppet below is what I'm currently focused on. Thanks.

const TODAY = days(new Date());
const res = Math.round(400 - 300 * ((DEADLINE - TODAY) / (DEADLINE - START)));

The Javascript code executes sequentially. On line 7 you set the constant days. A constant is meant to never change. However, you set it again on line 28? I'm not sure why.

Same problem with the const DEADLINE. It's a constant, and yet you're trying to set it to two different values, on line 8 and then again on line 29. You can't do that. If you need the value to change, you need to make it not a constant. The constants START and TODAY just need to be set once as well.
