Rick is correct.

You're currently using the button click action to assign the value of the variable, but that won't automatically execute the Conditional Action you've created to Show the text caption. 

Unfortunately, you cannot currently use one Advanced Action to execute one or more OTHER Advanced Actions. So instead of using your button click action to just do the variable assignment, you'll need to redesign the way your interaction works so that the button click executes a Conditional Action with a number of clauses.  The first clause will be assigning the variable value, and then subsequent clauses will be used to check the current value of the same variable and show or hide captions.

Lilybiri's blog has many examples of similar interactions.

Becky,

Rod and Rick pointed in the correct direction. The event you will be using to trigger the advanced aciton is the Success event of the button. This means that all actions have to be in the script, in the correct sequence. It will be a conditional action with multiple decisions Your user var has a start value of 0, change this to 1 in the definition of the variable. The first decision will then be:

IF v_click =1

   THEN Show TC1

                Expression v_click = v_click + 1

The second decision, just change the ID of the textcaption and the value of v_click to 2, same for decisions 3, 4 & 5

But you have to hide the previous TC1 as well

The last decision will check if the var is greater then 5 and act accordinglty.

Cannot show example, typing on a tablet, no Captivate on it

and lot of typos

PS thanks for comment on blog

@Rod Avoided having to add a first mimicked standard action by setting the value to 1 to start with

Wait a minute, shouldn't have tried this on a tablet. Think you'll have to reverse the decisions, because indeed now if v_click = 1 you'll increment and you get also the second decision resulting in correct.

Reversing: start with the highest value (6 I presume) and end with the lowest (1) for the decisions. So sorry, this is cumbersome because there is no easy way to change the sequence of the decisions, something I have  been asking for since long.

I'm so sorry and again on tablet. You need to show 4 Text captions, each click has to show one in the sequence TC1, TC2, TC3, TC4. And to track the clicks we use the created user var v_click. Both actions are done in one decision. When all captions are visible and user clicks again, a button has to appear. But not sure ifthis last  action is apart or together with the appearance of the last TC4. Decisions are executed in sequence:

Decision 1

  IF v_click is greater than 4

     THEN Show BtNext

Decision 2

IF v_click is equal to 4

   THEN Show TC4   

Expression v_click = v_click +  1

Decision 3

IF v_click is equal to 3
