Light switch wiring help
Ok so I just replaced the switches in my kitchen since we just had a huge remodel. I got the kitchen lights working but my laundry room light is not. I have attached the picture of the switches. I used the red and black wires. But I'm still confused on why only one switch is working. Any help would be appreciated. Thank you!

Welcome to the forums.
Looks like there are 2) three wire cables in that box. Not a common wiring method. The two cables could mean that those are on two different circuits.
Are the black wires tied together ?
Can you post a picture with switches pulled out a little so we can see all the wiring in the box ?
You can post pictures directly to the board as long as they aren't gigantic.

I see 2) three wire cables in the top and what looks like a piece of two wire UF (weatherproof cable) coming in an unprotected knockout in the center.
Both of those switches are using the same incoming power. That means that there are 5 wires in that black splice with the wirenut. My first guess is that one of the black wires to the switch is not getting power from that splice. You should be able to measure 120v to ground on the black wire on each switch.
Five wires can be a little tough to splice. I'd start there.
