Hello, I have been using the macro in Customized Flowcharts Using SAS® Annotation by Abhinav Srivastva to make the process of creating a sample size flowchart easier for my research group. https://www.lexjansen.com/wuss/2016/18_Final_Paper_PDF.pdf The provided macro code allows for 4 tiers in the flowchart, with each tier having three elements. We often have more than 4 exclusion criteria steps, so I'd like to edit this so more tiers are possible. Problem is, I've never used annotate before and my macro knowledge is somewhat limited! Here is the macro code, and I've made red the lines that I think should be edited, but haven't worked when I've tried them - I get an error message that says "a percentage point value lies outside 0 to 100 boundaries." If I can provide any more information, please let me know! Thanks.
