I tried to put in my new saddle and it keeps moving my saddle forward every time i try to tighten it up. how do i make sure the saddle doesn’t move and it is flat instead of tilting it?

Go to your closest bikeshop.
Hold the saddle at the angle you want as you tighten. Make sure all the hardware is clean (no excess grease and grime on bolts or mating surfaces). Use carbon grip paste for extra security
Common issue with these post heads. Knock out the two circular clamp parts that are set into the post, position them where ya want, then put the rest together and tighten everything down. They should spin, but they get compressed into the post when everything is tight.
The whole clamp mechanism should be able to rotate within the “loop” at the top of the post. They have a tendency to get reeeeeeally stuck if no one ever moves it. You need to use your saddle (or ideally a cheap old one) for leverage
The ring on the inside, where the bottom rails of your saddle make contact should move. They are conically shaped. Pop them out if they’re not moving. Put a little carbon grip paste on them to stop them slipping. Popped them back in lineup your saddle to the correct level angle and clamp away. Mine often gets stuck in that position, but once you take them out, clean them and lube with grip paste, they work a treat.
You have to readjust the internal part of the seat clamp too. The inner part sit on the tapper surface of the seatpost. It’s usually tightly fit. You need to loose it up a bit, so it can rotate freely like the outer part of the clamp.
Trek seat clamp system is not easy to adjust. The inner part of those seat clamp is awfully design.
