Masked menu Trouble

[nnewby]

I'm trying to create a menu like the one found on this site: Mountain Workshops only one that rolls up, not down.

I know it's masked, and on a sperate mc, but I can't for the life of me figure out how to get the mask to say moved down after i click on the menu.

I've looked all over the tutorials and downloaded the menu here. i just can't figure out how to make it roll up, not down.

It could be i'm just tired, but some of the script i'm not sure how to manipulate to get it to work if i try to recreate the menu else where to make it roll up, not down.

Thanks in advance
