How to spatial join two polygons

Question

There are two polygon layers both with no common attribute as the size of the polygons in one layer is smaller than the other. I need to count the number of the small polygons inside the bigger polygon using the "completely within" and "have their center in" match options. I am very new to ArcGis and I tried different options but the completely within match option values always result in 0 or sometimes 1. Can somebody please help with this?

Edit: I figured it out

Try running with Intersect just to see if that relationship method works. That will eliminate a question in your issue

My task is to use the Completely within method.
