In reply to nick sisonick. Yes they should. That's an indication that one or both switches aren't wired properly.

why would 1 switch only function properly if the other switch is on? they should both turn on independently correct?

In reply to Takouhie N Nate Jensen. Adding switches isn't my strong point but it sounds like you shouldn't have the black and red tied together now since they'll be running to separate switches.

What if I wanted to add a second switch to that light switch with a red wire? We are taking out a light in our bathroom, and adding a light with a fan. How can I add the other switch for the fan? I got it all to work on one switch, then I added the second set of wires, and tried to run a pigtail from the hot wires in the box (black and red pigtailed together) to the bottom screw, and the white wire on the top screw. In the attic had all whites and all blacks together. It flips the switch now, and the one switch that works turns off the lights over my vanity, not just the light over my toilet. I’m guessing the problem is in the attic again?
