I want to call the function upon the onmouseover="ParentFunction();" then kill it onmouseout="killParent();".
Note: in my code the parent function is called initiate(); and the killer function is called reset(); which lies outside the parent function at the bottom of the script.
I don't know how to kill the intitiate() function my first guess was:
var reset = function(){
return initiate();
};
here's my source code: any suggestions and help appreciated.
