Simulation Test with different score per attempt

Hi, for the simulation scenario, wherein we need to add score by using click box or text entry box, how can we update the score if each of the step in the simulation, there are 5 slides (attempts) which will have different score. Please note that users are given 4 attempts per step, and 1 see me. 

Step 1

1st attempt is correct, user will go to the next step and score will be 5

2nd attempt is correct (1st is incorrect), user will go to the next step and score will be 3

3rd attempt is correct (1st & 2nd attempts are incorrect), user will go to the next step and score will be 2

4th attempt is correct (first 3 attempts are incorrect), user will go to the next step and score will be 1

5th slide will be a see me and there will be no score, it will then go to the next step once the user watched the video demo (see me)

Step 2

1st attempt is correct, user will go to the next step and score will be 5

2nd attempt is correct (1st is incorrect), user will go to the next step and score will be 3

3rd attempt is correct (1st & 2nd attempts are incorrect), user will go to the next step and score will be 2

4th attempt is correct (first 3 attempts are incorrect), user will go to the next step and score will be 1

5th slide will be a see me and there will be no score, it will then go to the next step once the user watched the video demo (see me)

Step 3

1st attempt is correct, user will go to the next step and score will be 5

2nd attempt is correct (1st is incorrect), user will go to the next step and score will be 3

3rd attempt is correct (1st & 2nd attempts are incorrect), user will go to the next step and score will be 2

4th attempt is correct (first 3 attempts are incorrect), user will go to the next step and score will be 1

5th slide will be a see me and there will be no score, it will then go to the next step once the user watched the video demo (see me)

For the example above, the maximum score that user can get should be 15 points only. If the user get the 15 points, user should get a passing mark with 100% accuracy. Have tried execute advanced actions but either captivate adds up all the clicks (33) and user get a failing mark or the score that gets recorded is just for the 5 points, the other score automatically become zero.  Please note that captivate version is 11.8.0.586. Thank you
