Increment a global variable one button press at a time?

what I am trying to do is use a Switch index to controll movie clips
with a button to advance to the next case: statement and when I have reached the end
of the case: index go back to the case: 0; and start all over again.

what I need is a global variable and give it a value of 0
var clipsVariable:int = 0;
var goalreset:int = 10;

function onClick(event:MouseEvent):void{

is clipsVariable < goalrest

clipsVariable = 0;
else
add 1 to clipsVarable
call switch ();
}

I seem to have the somthing scrood up because the switch does not see the clipsVariable
and so go into an endless loop any ideas?
