How to stop the animation at a certain frame?

Question

Well, as the title already says, how can I stop my animtation at a certain frame. Is it only possible due setting up a timer, or can I also enter a code that stops at a certain frame?
And when I stop the animation, will my buttons still be able to get clicked?
Greetings,

Thanks for the usefull reply, the problem was that i forgot the add a new keyframe that's why I couldnt make it in the frame I wanted.
I will have between 15 and 20 buttons that need to be able to get clicked when my animation is stopped, I first imported them to my library, then placed everything where I wanted it to be. Then created them as a Symbol (Selected Button!). Then I created instance names for every single of them.
With the code that's downstairs I want to let my animation go to frame 200 when I click on the button "Middenknop" while the animation is paused. But now i get this error:
TypeError: Error #1009: Kan geen eigenschap of methode benaderen via  een verwijzing naar een object dat null is.

Here's the code I am currently using:
import flash.events.MouseEvent;
//---Middenknop eigenschap verandering---\\
Middenknop.addEventListener(MouseEvent.CLICK, basisClick);
function basisClick(event:MouseEvent):void{
    gotoAndPlay(200);
