You need to provide data in an useable and secure format. 

And in rectangular format because what you share is the desired report alike outcome. 

Beware of sharing excel files. many helping hands here won't open it. 

When working with proc report you come from a rectangular data format and you can shape it according to your needs. 

and use the code window for posting code.

Please share your data as SAS data step code, and not in any other format. You can use this macro to create such code from your SAS data set. Agreeing with @acordes , most of us will not download or try to use Excel files.
