How do i check the localplayer's humanoid health between a certain point?

##Problem:

You're using 2 operators in the same line, which cannot work

EX:

if humanoid.Health <60 and > 50 then

The above code will not work because you've already inputted an operator

##Simple Fix:

Just remove one of the operators and that will fix your issue.

NOTE:

It's also good to constantly check for the player's health by either using a loop or .HealthChanged or the code will only check once.

Fixed Code:

local humanoid = game:GetService("Players").LocalPlayer.Character.Humanoid
humanoid.HealthChanged:Connect(function(health) 
	
if humanoid.Health < 60 and  50 then
	print ("yes") -- it's there just for debugging purposes
elseif humanoid.Health < 50 and 40 then
	script.Parent.ImageLabel.ImageTransparency = 0.8
end
	
end)

Or if you wanted it to do it only once just remove the connect function:

local humanoid = game:GetService("Players").LocalPlayer.Character.Humanoid
	
if humanoid.Health < 60 and  50 then
	print ("yes")
elseif humanoid.Health < 50 and 40 then
	script.Parent.ImageLabel.ImageTransparency = 0.8
end
