On my final slide I have created two buttons.

The 'PASS' button which should only show if the score is greater than or equal to 80% or 8 out of 10 and will then go to slide X.

The 'FAIL' button which should only show if the score is less than 80% or 8 out of 10 and will then go to slide Y.

I am not sure if it is failing at the 'total' objective level or at the slide level but I cannot get the buttons to show and hide according to the conditions.

Here is what I am using attached to the thumbnail navigator action:

DISPLAY ->hide the PASS button
DISPLAY ->hide the FAIL button
IF SCORE (Objective="total", Source= , Condition= >=, Score=8
*DISPLAY ->unhide the PASS button
IF Score (Objective="total", Source= , Condition= <, Score=8
*DISPLAY ->unhide the FAIL button

The * means a space so when the IF is checked the action only occurs if the conditions match.

I have tried 'IF SUCCESSSTATUS' as well and also tried to apply the action to the buttons themselves with no success. I know I am making a small mistake somewhere that I just can't seem to find. PLEASE HELP
