HTML question (&nbst)

[Travis Roy]

My manager is making a new contact DB for our company, and it's great. 
The problem is that for spaces he's using &nbsp and it shows up in my 
firefox, but not in his IE.

I'm positive it's that he's doing it wrong, but searching for it in 
google is hard because I get a ton of other pages that are using it 
wrong rather then a result explaining how to use it.

Anyway, can anybody show me a proper example of using nbsp?
