Is it IF or vlookup or both?

Hello,

please beware with me, if my question is to simple... I'm working on developing my excel skills... but they are scarce...
i have a large worksheet with different data
it lists clients salary ranges (see below) I want to be able to match it the lower Bound range (also below).
I have the following data:
Range Lower Bound

under $30,000 0
$30,000 - $60,000 30,000
$60,001 - $90,000 60,001
$90,001 - $120,000 90,001
Over $120,000 120,000

How do i tell the cell when there is salary range 'under $30,000' i want to see 0, and so on for the others?

Thanks in advance.
