Overloaded Meltdown script not working?

I am making a core game with the Overloaded Meltdown. What I did was test the Overloaded Meltdown I made. But if the freezedown script was enabled and I enabled the Overloaded Meltdown script, the Overloaded Meltdown script does nothing. But if the freezedown script was disabled and I enabled the Overloaded Meltdown script, it works properly. Any help would be appreciated!

Script names: Overloaded Meltdown: OverMeltdown Freezedown: Freezedown
