Help with portal ball reciever

Hello, I need more help from you guys. The ball catcher I built has a problem in that it won't catch the ball; it will register the ball, do the animation, and activate whatever is linked to it, but it will not catch the ball. In other words: the ball activates the ball catcher but the catcher doesn't cease the motion of the ball, so the ball continues bouncing off of walls.

I believe that this is the problem:

!! func_tracktrain(ball_trap_door,SetSpeed) doesn't match type from path_track(path_ball_trap_02)

ball_trap_door is the func_tracktrain and path_ball_trap_02 is one of the path_tracks that I believe is used to catch the ball.

Then again, mabye I'm completely wrong. However, I do need help in making the catcher catch and hold that ball. To make it easier, I will post the outputs on the ball catcher trigger:

All output commands are OnStartTouch.

Target entities --> Input --> Parameter -->Delay (if not posted, it's 0) none are only once

trigger_ball_trap -> Disable
energy_ball_launcher_lvl7 -> Disable
filter_ball ->Kill
ball_trap_ball_01 -> Enable
ball_trap_01 ->Setanimation ->Close
ball_trap_spotlight ->Lightoff
ball_trap_door ->SetSpeed->.5->0.00
ball_trap_sound->Playsound
door_rotating01->Open
door_rotating02->Open

What the enties are:
trigger_ball_trap is the trigger brush that activates the catcher
energy_ball_launcher lvl7 is the ball spawner on the ball launcher
filter_ball is the ball filter for the catcher
ball_trap_ball_01 is the ball model that fits inside of the ball catcher on activation
ball_trap_01 is the ball catcher model
ball_trap_spotlight is the light that is emitted from the catcher
ball_trap_door is the func_tracktrain
ball_trap_sound is the sound that plays on activation
the door_rotating are doors that are activated by the catcher.

Thanks in advance!!
