Thanks for your reply, I actually would like to display a text box if both resting and excercising condtions are met not "either" The problem I am having is that the text box displays even when Hear_Rate=100 when resting and Heart_Rate=60 when exercising , so it's basically applying each conditionfor example heart_rate=60 ...

I am going crazy here, I am newbie, I am using the condition below:  not((:Heart_Rate = 60 and (Stage= 1)) and ((Heart_Rate= 100 and (Stage= 2)))) I am trying to show a text box  based on a value of  heart rate when person is resting(Stage=1) and Exercising (Stage=2) However this expression shows works vice versa ...
