Help a pregnant lady with her light switches

Hello! I just replaced the light switches in my hallway to new ones-there were no issues before. I have a hallway light that can be activated by two switches--one on each end of the hall. The problem is that if the light is turned on by one switch--it cannot be turned off by the other switch. In other words, I have to turn the light off from what ever switch it was that turned it on in the first place. How can I fix this problem, it only happened once I replaced the switches. They are 3 way.

Welcome to the forums.

With three way switches there is one screw a dark color like black or brass and two silver screws. The dark screw is the common screw so what ever wire came off the old switch dark screw must go on the new switch dark screw. The other two don't make any difference.

It doesn't make a difference what screws are on what side..... the dark screw is the important one.

Let me know if you forgot which wire was the common one. We can find it.
