I am going to assume that you make these charts in advance. And, you put in the demographics, etc.
The part I don't understand is what no shows you want to pull up? All no shows today? (Which would simply be in your schedule for that day). All no shows from a certain time frame prior to a certain date. Generally, if I want to pull up certain charts later I enter data ahead of time into certain fields. I would enter Asthma into Misc 3 and then search for Asthma there and all patients in the study would pop up. It would be easy to do a date by entering 030415. But, I would be using the operator =. There are many fields you can populate to search for. But, I guess I would need to know more about what you are trying to do.
Sorry.
