Use
if 105<h & h<120
and
elseif 100<h & h<105

where and how do you call your function? for example if h = 100, you should call it like this:
Newfunction( 100 )
or
h=100;
Newfunction(h)

do i have to assign this value in my GUI function. because I have assigned a value for h and wrote the function but still keep getting error messages

as I see it now, you have assigned a value for h, but you're not supplying it to the function you wrote. There are two ways to overcome this.
1) supply the h as an input to your function every time you call it by calling your function like this: Newfunction(h) instead of: Newfunction
2) convert your function to a script. scripts don't require input, but are able to use all the current variables.
I'm no GUI-guru, so I don't know what is the best approach for your problem
