I’m having issues where my number either updates too slow or incorrectly, I’m not too sure which or if either but any help would be apricated.

Could you give us a more detailed description of the problem? Like, what’s happening exactly?

#3

Swap this out for

hum:GetPropertyChangedSignal("Health"):Connect(function(CurrentHealth))
#4

CurrentHealth becomes nil, I don’t think the property gets passed same as HealthChanged does.

#5

I’ll do you one better, heres exactly whats happening

as you can see in the script and in-game it seems the + health is rounding up rather than down, and the elseif statement isnt updating right
