Remote event fires but doesn't receive?

For some reason my remote event fires fine with other scripts besides the current one I am using, I tried other scripts and it worked fine I also tried created multiple copy scripts to see if it worked and no luck. Can I get some help debugging this?

The bottom is where the remote event should be received but it doesn't pick up the event being fired, and yes I checked everything over multiple times but it still won't pick up the signal.

Also, the script is in ServerScriptService and I tried putting it in other places but got the same result.

local MaxPetsAllowed = 100 -- just for testing!
