Try it like this:
if (parseInt(l,10) > parseInt(h,10))
or for floating numbers you can use
if (parseFloat(l,10) > parseFloat(h,10))
or simply use
Number()
You need to convert them to numbers:
if(+l > +h){
The unary plus operator will convert the string value to numeric value. See this question for more details:
What's the significant use of unary plus and minus operators?
