I'm still messing up!

I'll try to explain what I've done so maybe you can see what it is I'm doing wrong.

The page is set to three columns with 1 cm margins all round.

The tab stop position is set at .5cm
The default tab is set at 1 cm
The alignment is set at 'right'
I chose the dot leader (which is the #2 option)
I clicked 'Set'
Then 'OK'

When I type a name and then tab no dots show up before the phone number.

What should I REALLY be doing?
