New 3-Way not working

I updated some switches in my house. The old switches were probably 20 years old. They worked fine but just looked bad. Anyway, I bought new 3-way switches from Lowe's and hooked them up exactly as the old ones were. After doing one 3 way the kitchen light still worked but when i added the second the way for the same light, the light stopped working. I hooked the old switch back up and it works. Obviously, I dont wire the new 3 way the same way as the old. Anyone have any ideas? This happened in a kitchen and also in a hallway. The wires came out of the the switch as follows: Black to top left, red to top right and white to bottom right. A second switch in another part of the house for a different light was wired like this: Black to top left, black to top right, and white to bottom right. Again, when I wired brand new switches just like the old ones, neither light worked.

Hope this makes sense. I appreciate any/all ideas you may have.

You can't go by the location of the screws. Look on the old switch and there will be 1 screw that's either marked "common" or a different color than the other 2 screws. This wire needs to be put on the black screw or "common" screw of your new switch. It doesn't matter which screws you put the other 2 on.

Other than the ground screw of
