Passenger side turn signals don't flash

[Silver Blue '97]

I had to replace the small bulb on the right side. When I want to make a right the front and rear bulbs comes on(but don't flash), and the right side bulb goes out. When the turn lever is in the neutral position the bulb on the right side is on, as is the other side. The left side works fine.

Any help will be greatly appreciated, thanks
