With fireball, do you mean a custom made dummy that slides towards a targeted location, or blizzards fireball that is sent upon a unit dealing damage and stunning him? For the knockback part, I would suggest you to use a knockback system. There are a lot of them around the forum just search for it and you will find one in no time.
Ok I searched and found one for you. Link. If you need further help just post again and ask.

not really what i was looking for
i need one where when it hits the Unit it flyes with the Fireball until the Fireball Disapeares like in the map "The Predator"
So... First of all do you have the trigger that creates the fire ball and makes it slide? If not you can use and modify my rocket launcher spell. Link. And if you want the unit to go with the unit you will need a trigger that moves the unit to the position of the fireball. You could add this to the rocket launcher as well by creating a unit group around the fireball, pick every unit in the unit group, move them to the fore ball's location.
I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
