Attempts at multiple click boxes

Create a user variable v_counter, with a default value of 0. Group the two click boxes in gr_cb

You don't tell what exactly has to happen when a click box is clicked, which is a pity. You need an advanced action for each click box if they need to have another command to execute, or one advanced action which can be the same for both click boxes, if there is no extra command necessary. The advanced action will have two decisions:

1. Decision 'Always', which is not conditional
     Extra command (if necessary)
     Increment v_counter by 1
2. Decision 'CheckAttempts'  which is conditional
     IF v_counter is equal to 3
      Hide gr_cb

There is no need for an ELSE part in the second decision

I would accomplish this by tying a variable to both click boxes.

Each time one of them is clicked it will increment the variable.

Also have the action perform a conditional check of the variable.

in a nutshell...

(not actual code to use but a representation)

++myVariable;

if (myVariable==3) {
  cp.disable("clickBox1");

  cp.disable("clickBox2");
}

After the third click - both buttons should fail to function.

Hope this helps.
