The loops & buttons in a game do not work

The loops & buttons in a game do not work

I am writing an applet (a type of guessing game) that could collect
responses over the net. The buttons do not work properly, I also have
trouble with loops, as well as can not figure out how to store user input
data. I would appreciate any help that you could give me some hints how to
fix these issues or improve this code.
i) See my semi working code here. 2) Program flowchart here.
In summary, the applet generates a vector of random numbers between 0 and
1 and using those numbers draws a few geographical shapes on the screen
that resemble a face (Chernoff Faces). The program asks the user to guess
whether the face is "good" or "bad", based on values that are mapped into
geographical shapes. The user has to either ACCEPT or REJECT the shown
face and indicate their level of confidence about this decision. After
answering the user receives feedback whether the decision was correct or
not, the points are awarded for correct assessments and points are taken
away if the assessment is incorrect. There are many rounds of this game,
and the goal is to be able to improve ability to assess faces.

My major concern are the loops, the "Next" (face) button (to restart the
loop). I have trouble in storing and recording the data, thus, I really
appreciate your comments regarding any of these issues.
The applet has the following sequence:
PHASE 1:
Instructions (page 1)
Instructions (page 2)
PHASE 2:
Start Guessing Game:
STAGE 1 (100 loops):
State 1:
Generate a vector of random numbers (e.g. 11 numbers
from 0 to 1).
Attach equal weights to each random number and
compute the mean value of these random numbers.
Draw geographical figures that use these numbers in a
special way that would resemble a face.
Ask user to "accept" or "reject" this face.
State 2:
Show decision feedback (score) to the user. The score
is computed as follows:
If mean value of random numbers is more X (e.g.0.5),
then it is a "good" face.
If mean value of random numbers is less that X
(e.g.0.5) then it is a "bad" face.
If user accepts a "good" face or rejects a "bad"
face, he made a good decision, and gains 1 point.
If user accepts a "bad" face or rejects a "good"
face, he made a poor decision, and loses 1 point.
STAGE 2(100 loops):
The weights should change assigning 0.9 and 0.1
weights to the first too values, and 0 weights to the
remaining values.
Repeat State 1 and State 2 for additional 100 rounds.
NOTE: Record the random values, weights, mean values, and
responses of the users for both rounds.
PHASE 3:
Finish the game by giving performance summary.
