If you're using the walkthrough - there are 2 sets of buttons: a left-right buttons and top-bottom buttons.
The numbers on the wt is based on the middle button of both.
The top-bottom set moves the tower up-down.
The left-right buttons turns the tower.
You have to raise and turn the tower so that it activates a flower. Then activate the rest.
Best to do the flowers on side then the other side of the tower.
