Problem with advanced action

Hi everyone,

I'm trying to write an advanced action that will only show text boxes in a quiz when the quiz is in review mode.

I did the following:

• Set up text boxes on the quiz question slides, hid them using the "eye" icon
• On the quiz  results slide I set up an execute advanced action on slide entry
• Set action type to conditional
• Set Perform action if all conditions are true
• Set actions to variable cpInReviewMode,  Set select comparison operator as “is equal to” and set literal as 1
• set each line of action as show with the name of the text box (2 lines of action set up)
• Set the “else” section so it “hides” each of the text boxes (2 lines set up)
  
• When saved and viewed the first quiz slide works as expected in "live" and "review" mode (i.e text is hidden when quiz is being taken but visible when it is being reviewed, BUT the second quiz slide always shows the text that should be hidden, irrespective of whether the quiz is in or not in review mode

Any ideas what I am doing wrong?
