Hi guys, you have all been very helpful in the past, so im hoping you can help me with this one bit of refinement. here is the code…

```auto
SetNextProject = function () {
	i++;
	ProjectPreloadB(currentArray*);
	if (i>=currentArray.length) {
		_root.mc_projects.mc_projectsLoadedB.mc_arrowF._visible=false;
	} 
	else (_root.mc_projects.mc_projectsLoadedB.mc_arrowF._visible=true)
};

```

The point of this code is to make button mc\_arrowF go away when the end of the array is reached. Its BASICALLY working, however when i load, say currentArray[18], the end of the array, the button doesn’t disappear until i press it again. Basically, the button doesnt disappear until currentArray[19]… even though currentArray.length=18. A

How can i fix this? any help would be appreciated!
