So, I read the link "How to ask questions the smart way" and perhaps I didn't state my question properly.
I have done google, MS Office and Forum searches on how to filter queries or reports so that only patients with multiple visits will show. The results of those searches only tell me how to get rid of duplicates. These are not duplicate records.
The goal is to see the changes in a patient's height and weight over time. So if we only saw a patient once, there is no change and therefore, no need to see them on the query or report. I don't care which one has the filter. Whichever is the easiest to write I suppose.
In my query, I have:
PtID
Age
DateVisit
Height
Weight
My Report is grouped by PtID (Age is 2nd field in that block of the report)
Detail is DateVisit, Height and Weight.
I'm also curious how I could have worded my search to find the answer. I think that peeved me more than not being able to solve this on my own.
