brick = game.Workspace.Brick
function onTouch(part) --the function
workspace.Brick:remove()
end
brick.Touched:connect(onTouch)
why wont it remove the brick?
You don't have to capitalize workspace, actually.
game.Workspace is preffered though.
But I wonder, why are you setting a variable at the top of the script if you aren't going to use it?
