Zero clicks

I started my adword campaign 4 days ago and zero clicks.

I dont get it. Ok my highest click value is 20cents but still I should get a total of about 40 clicks per day-according to to the google tool thing.
I'm on 2$ per day program--has only cost em the 5$ initial fee so far.

Is this usual or??

Have you tried putting the terms into google to see if they come up?

I've got terms that have never come in 4 months, but these are very targeted and probably worth still keeping just in case.

"40 clicks per day-according to to the google tool thing"

You cannot rely on this tool, it is like 99% way off the mark.
