How do I change the split screen effect in Game Maker 7?

I'm making a game with split screen multiplayer. It's kind of like Battlefield Bad Company. In multiplayer, player one can have an M249 SAW, an HS10, etc. In the SAW object, I made the rule that if you press Keypad 2, it deletes M249 SAW, and creates HS10 (a separate object). There is also a view changing script that changes the view number when the HS10 is created. The problem is, whenever I press Keypad 2, it doesn't delete M249 SAW and it doesn't create the HS10. I know the game reads the rule, because whenever I press Keypad 2, instead of doing what is said, it drops a "tactical insertion", or in other words it gives M249 SAW a new spawn point, so whenever player 2 kills him, player 1 spawns on where player 1 last pressed Keypad 2. Help?
