GROUP BY error message with IF statement

GROUP BY error message with IF statement

Hi, 

I'm reasonably new to coding so this may be a really simple fix (i hope anyway!)

I'm building a query table to identify cases for inclusion in a healthcare quality indicator as well as produce an output column that provides a true or false statement as to whether the indicator has been met. Query 1 below works fine but when I want to add another OR statement in the IF statement (shown in query 2 below query1) I get this: 
Error Details:

Query Error: Improper usage of GROUP BY clause.
Please ensure that all non-aggregate columns used in the SELECT clause are also used in GROUP BY clause.

**Query 1 - this works**

SELECT

Please can you advise why it's giving me the error message?
