How can i reload without a button?

So im making a Doom 1993 clone as a personal project and i cant figure out how to make it so that when the mag is empty it will automatically reload without pressing a button.

Here is a picture for my current set up:

I use this technic.
first, select your “remain bullet” variable, and in “Details” set “Replication” to “RepNotify”.

now a function created go to it.

now check if your bullet equals 0 so reload the gun automatically.
