Visible function for buttons of a slideshow not working

1

Whoever can figure this out: I’ll will deam you a genius!

I’m working with a dynamic slideshow that was already set up. Instead of thumbnails each image has a button that you click to see the image. I cant get the buttons to turn off for the categories that have less than 26 images. I put the site as it is so far up here: http://www.teamredstudio.com/sample/ljsalkinphotography/site

the button instance names are imgB1, imgB2, etc… they are in a container that is called: mc,collection_menu
with an instance name of: collection_Menu
basically in the script bellow the: visible=false is not working, is this the right syntax… what is wrong here…

Thanks you so much joseph aka teamred

// this is the main button to start the slide show
collButtHolder.Bali.onRelease = function() {
	//move the to menu down to reveal the slide show components
	slide(collButtHolder,-155);
	slide(hide,725);


	// call the function to set up slide show or reset it you had other buttons
	// this is where you set your path to the photos and how many photos are in that folder.

	collectionMenu.bName.text = "Bali";
	collectionMenu.nValue=(1)
	_root.changePhoto(-1);
