Scratch

I have a lab that is due tonight and despite several attempts I can't seem to do this on my own. I asked the professor during class and she refused to assist any of us with how the program works. She would rather we spent countless hours figuring out the program. I currently work full time and have several classes so this is a bit difficult jumping into a fresh new program.

Lab 1:
Goal: To create a program that will make a sprite dance including music and keyboard control
Procedure
1. Select a Sprite. Can either use pre-built ones or use the paint program to create/modify Sprite and costume.
2. Build a script starting with motion blocks. The script is built iteratively. Add a block and then run it to see what happens. Modify the existing blocks and add new ones to get what you want.
3. Use a forever loop to continue the dance.
4. Add a green flag hat to control when the dance happens (hitting the green flag starts it, the red button stops it)
5. Add a "when key pressed" hat to change color on a key press
6. Add a second sprite and synchronize the dance with the two sprites.
Save the program to turn in at a later date

I've attempted things but I can't seem to make it do that much. I've tried to run a continuous set of instructions but I would either end up with a sprite not moving, which was very odd, or a sprite bouncing from wall to wall.

Suggestions?! please help.
