Halachic Conclusion:
How do we conclude l’halacha regarding;
Placing a צורת הפתח on an opening wider than 10 Amos?
Placing a צורת הפתח on multiple openings which are פרוץ מרובה על העומד and less than 10 Amos ?

Major Question:
The Rambam concludes that each situation individually a צורת הפתח is valid. However when both are combined in a case of an opening wider than 10 Amos and פרוץ מרובה על העומד than it is disqualified.
If each situation independently is valid, why is the combination deadly?
Our Gemara said the source to disqualify a צורת הפתח when there are more openings than closures – פרוץ מרובה על העומד is from the halacha of Rav who rules a צורת הפתח can not close an opening wider than 10 Amos. Since the Rambam concludes a צורת הפתח is valid on an opening wider than 10 Amos where is the source to disqualify it when there is פרוץ מרובה על העומד ?
